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.

Pythagorean triples are a2+b2 = c2 where a, b and c are the three positive integers. These triples are represented as (a,b,c). Here, a is the perpendicular, b is the base and c is the hypotenuse of the right-angled triangle. The most known and smallest triplets are (3,4,5).
How do you find the hypotenuse of a 45 45 90 triangle?
The Pythagoras theorem, also known as the Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle. Or, the sum of the squares of the two legs of a right triangle is equal to the square of its hypotenuse.

In any 30-60-90 triangle, you see the following: The shortest leg is across from the 30-degree angle, the length of the hypotenuse is always double the length of the shortest leg, and you can find the length of the long leg by multiplying the short leg by the square root of 3.
Is 6 8 10 a right triangle?
Today, many people are familiar with Pythagoras because of the famous Pythagorean Theorem, which is a mathematical formula for finding the length of the hypotenuse of a right triangle. It states that the sum of the squares of the two non-hypotenuse sides of the triangle is equal to the square of the hypotenuse.
What is the length of the hypotenuse in a 45-45-90 triangle if the length of a leg is 6 cm?
Because the ratio of the area of a right triangle to the square of its hypotenuse is the same for similar triangles, the relationship between the areas of the three triangles holds for the squares of the sides of the large triangle as well.
What is the length of a leg in a 45-45-90 triangle if the hypotenuse is 10?
The Pythagoras' theorem can be used to find the length of the third side of the right-angled triangle if the lengths of the other two sides are provided. The Pythagoras' theorem can also be used to determine whether a triangle has a right angle (90°).
How do you find the long leg of 30 60 90?
The Pythagorean theorem is a simple formula which uses the squared value of a and b; for example "a=3 and b=4, what is the value of c?" you square a (3^2=9=a) and b (4^2=16=b) and add the 2 values (9+16=25) to get to c.

Sines and cosines for special common angles
It is found in an isosceles right triangle, that is, a 45°-45°-90° triangle. In any right triangle c2 = a2 + b2, but in this one a = b, so c2 = 2a2. Hence c = a√2. Therefore, both the sine and cosine of 45° equal 1/√2 which may also be written √2 / 2.

How do you find missing angles?
Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse . No matter the size of the triangle, the values of sin(θ) and cos(θ) are the same for a given θ, as illustrated below.
Can a triangle have 2 30 degree angles?
Tangent, which is commonly abbreviated to three letters as T-A-N, is the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle. The adjacent side is the one touching the angle that is NOT the hypotenuse, which is the side opposite the right angle.
How to do trigonometry?
Thus, 2π radians is equal to 360 degrees. . Multiplying both sides by 360° gives 360° = 2π rad.

What is sin θ?
In a 30 ° − 60 ° − 90 ° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is times the length of the shorter leg. To see why this is so, note that by the Converse of the Pythagorean Theorem, these values make the triangle a right triangle.
