Root Explanation

Hypotenuse → It is formed from the Greek "hypoteinousa" (meaning stretching under) which is derived from "hypo-" (meaning under) and "teinein" (meaning to stretch). The word refers to the side of a right triangle that stretches under the right angle, opposite the right angle.

Memory Tip

Imagine a triangle where the hypotenuse is the side that 'stretches under' the right angle, helping you remember that it is the longest side.
