a2 + b2 = c2
subtract
In real life its not useful, unless you're going to need geometry in the career you choose.
They are: a2+b2 = c2 c2-a2 = b2 c2-b2 = a2
Pythagoras theorem is always used in right angle triangles. It can be used to find any of the third side is two sides are given, It can also used to find the area of cone if slant height or anything else is missing.
the theorem is used for right triangles. it means the two smaller sides squared and added together equal the hypotenuse squared. the three ways to use it will let you find the third side if you were given two other sides. a2 + b2 = c2 b2 = c2 - a2 a2 = c2 - b2

Four great mathematicians who contributed to geometry are Pythagoras, Euclid, Rene Descartes and Bernhard Riemann. Pythagoras contributed the Pythagorean theorem. Euclid's geometrical works helped develop geometry in many ways. Descartes contributed Cartesian Geometry. Riemann's contribution can be seen in the form of Riemannian Geometry.
There are three main ways to prove to triangles congruent. If all the sides match, if a side then an included angle and the next side and last angle-side angle. SSS, SAS. ASA
It's Pythagoras...*gives a hurt look*... Anyway, Pythagoras was a Greek philosopher/mathematician (this was common in those times) who pioneered geometry in more ways than one, but is most notably known for discovering the relationships among the sides of a right triangle, thus the Pythagorean Theorem: a2+b2=c2.
Applying the binomal theorem, multiply all the digits.1x2x3x4x5x6x7x8x9x10.You probably need to practise arithmetic more than I do.
In his Pythagorean Brotherhood , they would try to come up with new ways of doing maths all the time.
