The Pythagorean theorem is crucial in various fields, including construction, manufacturing and navigation, enabling precise measurements and the creation of right angles for large structures. It ...

In this triangle \(a^2 = b^2 + c^2\) and angle \(A\) is a right angle. Pythagoras' theorem only works for right-angled triangles, so you can use it to test whether a triangle has a right angle or not.

If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.

For centuries, the Pythagorean Theorem has occupied a unique position in mathematics: both elementary and profound. Its ...
