Can a 1 2 3 triangle exist?
As others have already pointed out, you cannot have a triangle with one side being 1 in length, the second side being 2 in length, and the third side being 3 in length.
Can 1 1 and 2 make a triangle?
There is no such triangle, for the simple reason that for you to have a triangle, two of the sides must have a sum greater than the third side. This is not fulfilled with your triangle, as the longest side (2 parts) equals the sum of the two other sides (1 part each).
Which triangle is impossible to create?
The Penrose triangle, also known as the Penrose tribar, the impossible tribar, or the impossible triangle, is a triangular impossible object, an optical illusion consisting of an object which can be depicted in a perspective drawing, but cannot exist as a solid object.
What if the angles of a triangle are in the ratio 1 2 3?
∴ Angles are 30∘,60∘,90∘
What is the 30 60 90 triangle rule?
The 30-60-90 triangle rule is for finding the the lengths of two sides when one side is given. The shorter side is opposite the 30 degree angle, the longer side is opposite the 60 degree angle, and the hypotenuse is opposite the 90 degree angle.
Can 4 7 11 make a triangle?
4 + 7 = 11. 11 is not greater than 12, so these sides cannot make a triangle. 9 + 14 = 23. Since 23 is greater than 22, these three sides can make a triangle.
Can 3 4 8 make a triangle?
The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, , 3 in., 4 in., 8 in. do not form a triangle.
Can 3 6 8 be a triangle?
For three lengths to form a triangle, the sum of two of the sides has to be more than the length of the third line. 3,6,8 or 3,6,7 will form triangles.
Can 3 4 5 make a triangle?
Yes, 3-4-5 makes a right triangle. Putting those numbers into the Pythagorean theorem and solving proves that they make a right triangle.
Can the impossible triangle exist?
It is impossible for the Impossible Triangle to exist because in order for it to exist rules of Euclidean geometry would have to be violated. For example, the bottom bar of the tribar is represented as being spatially located to both the front of, and, at the same time, the back of the topmost point of the tribar.
Can a perfect triangle exist?
However, if we change the geometry to taxicab geometry, all circles are squares, although not all squares are circles! A perfect triangle can't exist in our universe because of the definition of “perfect”.
Why can some triangles not exist?
If angle A is acute, and h < a="">< b,="" two="" possible="" triangles="" exist.="">If angle A is obtuse, and a < b="" or="" a="">, no such triangle exists.
What is the value of sin 30?
The exact value of sin 30 degrees is ½.
What if the angles of a triangle are in the ratio 1 1 2?
In a triangle angles are in the ratio 1:1:2, then the triangle is. Isosceles. Equilateral.
Do right angled triangles add up to 180?
Explanation: The internal angles of a triangle always add up to 180 degrees, and it was given that the triangle was right, meaning that one of the angles measures 90 degrees. This leaves 90 degrees to split evenly between the two remaining angles as was shown in the question.
What is the 45-45-90 rule?
A 45-45-90 triangle is a special type of right triangle, where the ratio of the lengths of the sides of a 45-45-90 triangle is always 1:1:√2, meaning that if one leg is x units long, then the other leg is also x units long, and the hypotenuse is x√2 units long.
Is a 345 Triangle a 30-60-90?
No. The sides of a 30–60–90 triangle are in the proportion 1 - √3 - 2, not 3–4–5. Or, looking at it the other way, the angles of a 3–4–5 triangle are about 36.87°, 53.13° and 90°.
What is the angle of depression?
In trigonometry, the angle of depression is the angle formed between the horizontal line and the line of sight when we look downwards at an object. In this angle, the object at which we look is always placed below the horizontal axis or line.
Is 7 8 9 a triangle?
Hence the triangle with sides 7 cm, 8 cm and 9 cm is a scalene triangle.
Can 2 9 12 make a triangle?
No. The sum of any 2 sides of a triangle must be greater than the third side. This is because the two shorter sides cannot possibly touch each other if placed at either end of the longest side. Since 2 ft+9 ft<12>it would not be possible for a triangle to have sides of these lengths.

Therefore we cannot have a triangle with sides 4, 5, 9 simply because we would need to satisfy 4+5 > 9 which is impossible.
Can 2 3 5 be a triangle?
NO. For three lengths to make a triangle, the sum of any two sides must be greater than the third one. There are no exception to this.
Is 2 3 7 a triangle?
The (2,3,7) triangle group is the group of orientation-preserving isometries of the tiling by the (2,3,7) Schwarz triangle, shown here in a Poincaré disk model projection. To construct the triangle group, start with a hyperbolic triangle with angles π/2, π/3, and π/7.

Is 9 12 15 a right triangle?
where h is the hypotenuse (that is, the longest side of the triangle). The sum of the squares of 9 and 12 does indeed equal the square of the hypotenuse, h=15; therefore, the triangle is indeed a right triangle. Therefore, final answer: Yes, the triangle with sides 9,12 and 15 is a right triangle.
Are there infinite triangles?
It turns out that there are an infinite number of right triangles with integer edges, which is relatively simple to see.
What is the impossible shape?
Penrose triangle (tribar) – first created by the Swedish artist Oscar Reutersvärd in 1934. Roger Penrose independently devised and popularised it in the 1950s, describing it as "impossibility in its purest form".
Can you make a Penrose triangle?
Also called the Penrose triangle, this object looks on paper like a solid, three-dimensional object, but it's actually impossible to make in a true three-dimensional form.
What is the strongest 3d shape?
The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape. The reason being is that stress is distributed equally along the arc instead of concentrating at any one point.
Are hexagons stronger than triangles?
The list of structures from strongest to weakest are: (1) cylinder (averaging 164.8 kg of load at crushing weight), (2) hexagon (averaging 136.8 kg of load at crushing weight), (3) square (averaging 127 kg of load at crushing weight), (4) triangle (averaging 89.2 kg of load at crushing weight).
Is A circle stronger than a triangle?
circle will be strongest if the stress is distributed along the circumference(like bubble) while triangle will be strongest if the stress is on only one corner along the perpendicular axis(like pizza slice held vertically).
What triangles Cannot be solved?
A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called vertices, are zero-dimensional points while the sides connecting them, also called edges, are one-dimensional line segments. The triangle's interior is a two-dimensional region.
Do triangles exist?
Patterns and shapes in nature are visible all around us; these patterns can be found in many different contexts and include shapes, symmetries, spirals, arrays, cracks and stripes. Triangles can be found in so many places in the natural world; grass, rocks, leaves and flower petals all display triangles in nature.
Do triangles exist in nature?
The value of sin 0 degrees is 0.
What sin is 0?
Start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. Therefore, sin 90 degree equals to the fractional value of 1/ 1.
Why is sin 90 equal to 1?
After bisecting the angle, it would become 30° and length of the side will be ½ (the side opposite to the angle 60 degrees which equal to 1), this way we get sine 30° as ½.
Why is sin 30 1?
A full revolution is 360 degrees, which is sometimes considered 0 degrees so the largest integral angle would be 359 degrees. Unless this is trigonometry where you can have an infinite number of rotations in either direction, so the largest possible angle does not exist (infinity).
What is the largest angle?
In geometry, an isosceles triangle (/aɪˈsɒsəliːz/) is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
What is the largest angle of a triangle?
The 30-60-90 triangle rule is for finding the the lengths of two sides when one side is given. The shorter side is opposite the 30 degree angle, the longer side is opposite the 60 degree angle, and the hypotenuse is opposite the 90 degree angle.
What is isosceles line?
A polygon is any 2-dimensional shape formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides.
What is a cute angle?
sin 45° = 1/√2 (Why & How?)
What is the 30 60 90 triangle rule?
In any triangle, the side opposite the smallest angle is always the shortest, while the side opposite the largest angle is always the longest. You can see how that applies with to the 30-60-90 triangle above. Triangles with the same degree measures are similar and their sides will be in the same ratio to each other.
Is A triangle A polygons?
A 45-45-90 triangle is a special type of right triangle, where the ratio of the lengths of the sides of a 45-45-90 triangle is always 1:1:√2, meaning that if one leg is x units long, then the other leg is also x units long, and the hypotenuse is x√2 units long.
Is sin 45 root 2 over 2?
Type of triangle is Obtuse Scalene triangle. Well, lay down the line of length 6 first. The other two, since 3+4 is only slightly bigger than 6, must form an obtuse angle. So the triangle is obtuse.
Why does every 30 60 90 triangle have the same side ratios?
The main ratio that we use to find the angle of depression is tangent. The angle of depression may be found by using this formula: tan y = opposite/adjacent. The opposite side in this case is usually the height of the observer or height in terms of location, for example, the height of a plane in the air.
How do you find the short leg of 30 60 90?
The term angle of depression denotes the angle from the horizontal downward to an object. An observer's line of sight would be below the horizontal. Note that the angle of elevation and the angle of depression are congruent .

Triangle inequality theorem of a triangle says that the sum of the two sides of a triangle is always greater than the third side. Thus, a triangle with side lengths as of 15 units, 12 units and 9 units exist.
Does a triangle with 15 12 9 exist?
The only condition for three sides to be able to form a triangle is that no single side may be larger than (or equal to) the other two combined. Since the largest side, 12, is less than the sum of 9 and 11, there's no problem.
Can 11 12 9 make a triangle?
In the diagram △ABC is a 2-3-4 triangle, but think of it also as a generic a-b-c triangle. The exterior angle bisector at A meets the extension of ¯BC at D; let d:=|¯CD|.
