The relationship that, in a right-angled triangle, the squares of the two shorter sides add to the square of the hypotenuse.
Revise: Pythagoras' TheoremPythagoras’ theorem still describes a flat right-angled triangle. A 3D problem may contain more than one such triangle, so find one missing length and then use it in the next triangle.
