AI overview

A triangle is a basic geometric shape made up of three corners (called vertices) and three straight sides (called edges) that connect them. Triangles are important in geometry and mathematics because their internal angles always add up to 180 degrees, which is a fundamental property that makes them useful for understanding shapes and solving practical problems.
