Who is father of triangles?
Pythagoras of Samos was a famous Greek mathematician and philosopher ( c. 570 – c. 495 BC). He is known best for the proof of the important Pythagorean theorem, which is about right angle triangles.
Who developed triangles?
Pascal's triangle was invented by Blaise Pascal (1623-1662) in 1653. Although it has been named after blaise pascal, there have been traces of the triangle, long before Blaise Pascal was born.
Who named the triangle?
The triangle is named for Blaise Pascal – however, possibly the earliest discovery of the triangle was by the Islamic mathematician Abu Bekr ibn Muhammad ibn al-Husayn Al-Karaji who was born in Baghdad, Persia – now Iraq – in 953. His most important work was a treatise on algebra called Al-Fakhri.
Who discovered the triangle theorem?
Pythagoras found out that for a right angle triangle (with one of the angles being 90o), the square of the hypotenuse is equal to the sum of the squares of the other two sides: a2+b2=c2. In other words, the green square's area (with area c2) equals the sum of two others.
When was the triangle invented?
The triangle was first introduced into the world in the 16th century, but it is actually a descendent of the ancient Egyptian percussion instrument called the sistrum, which was used for worship and other religious purposes.
Where did the triangle come from?
Some scholars believe the triangle to be a direct descendant of the ancient Egyptian sistrum. Others do not go quite so far, referring to the triangle as being "allied" with the sistrum throughout history, but not a direct descendant.
Who discovered the 3 4 5 triangle?
The Egyptians knew of this relationship for a triangle with sides in the ratio of "3 - 4 - 5". So the Pythagorean theorem states the area h^2 of the square drawn on the hypotenuse is equal to the area a^2 of the square drawn on side a plus the area b^2 of the square drawn on side b.
Who invented geometry?
Euclid, often called the father of geometry, changed the way we learn about shapes with his 13-book series, Euclid's Elements. He used basic ideas called axioms or postulates to create solid proofs and figure out new ideas called theorems and propositions.
Who invented triangle and why?
Although other mathematicians in Persia and China had independently discovered the triangle in the eleventh century, most of the properties and applications of the triangle were discovered by Pascal. This triangle was among many of Pascal's contributions to mathematics.
How is a triangle named?
The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right. An isosceles triangle is a triangle with two congruent sides and one unique side and angle. Ex. An equilateral triangle is a triangle with three congruent sides and three congruent angles.

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.

Both of these civilizations used algebra in different ways and for different reasons, but it's generally accepted that it was the Babylonians who first made basic use of algebra and pioneered its beginnings in the field of mathematics. There is evidence of this that dates back as far as 1900 to 1600 BC.

The Greek letter delta (δ, or ∆) is often used to indicate such a change. If x is a variable we write δx to stand for a change in the value of x. We sometimes refer to δx as an increment in x. For example if the value of x changes from 3 to 3.01 we could write δx = 3.01 − 3=0.01.
What does ∆ mean in math?

Acute Angle Degree
The degree of an acute angle measures less than 90 degrees, i.e. less than a right angle. The examples of acute angle degrees are 12°, 35°, 48°, 65°, 80°, 89°. Hence, the acute angle degree ranges from 0 degrees and less than 90 degrees.

Answer and Explanation:
Note that for any triangle, the sum of the lengths of any two sides is greater than the third side. Therefore, we must do the test if the given lengths can form a triangle. Therefore, it is possible to form a triangle with side lengths of 8, 7 and 9 cm.
