ANSWER :
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
Area: ½ × base × height
Perimeter: sum of side lengths of the triangle
Number of vertices: 3
Number of edges: 3
Internal angle: 60° (for equilateral)
