Root Explanation

Circumcircle is formed from "circum-" (meaning around) and "circle" (from Latin "circulus", meaning a small circle). The word refers to a circle that encompasses a polygon, touching all its vertices, hence a circle that goes around it.

Think of 'circum-' meaning around, and 'circle' referring to a round shape. This helps you remember that a circumcircle is a circle that goes around a shape, touching all its corners.
