I.m assuming you are talking about the pythagorean theorem ( a2 + b2 = c2) and thus the guy
given credit for it is Pythagoras
Euclid, a Greek mathematician, is credited with creating the theory of solving right angles. His work is known as Euclidean geometry, which laid the foundation for modern geometry.
The theorem states "If two angles are both supplementary and congruent, then they are right angles."
All right angles are the same.
All right angles are the same
to find the angles and sides of a right traingle
If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.
to find the angles and sides of a right traingle
There are no right angles in a square based pyramid, so Pythagoras and his theorem are not involved.
complementary
Use the pythagorean theorem.
Pythagoras. a squared + b squared = c squared.
It enabled them to make right angles - useful in construction.
