# G 1 2 3 the pythagorean theorem

For example, in spherical geometry, all three sides of the right triangle (say a, b, and c) bounding an octant of the unit sphere have length equal to π /2, and all its angles are right angles, which violates the pythagorean theorem because a 2 + b 2 ≠ c 2.

The pythagorean theorem is named after the greek mathematician pythagoras (ca 570 bc—ca 495 bc), who by tradition is credited with its discovery and proof,[2][3] although it is often argued that knowledge of the theorem predates him.

However, right triangles with non-integer sides do not form pythagorean triples for instance, the triangle with sides a = b = 1 and c = √ 2 is a right triangle, but (1, 1, √ 2) is not a pythagorean triple because √ 2 is not an integer moreover, 1 and √ 2 do not have an integer common multiple because √ 2 is irrational.
