Triangles Triangle A triangle is a closed figure in a plane consisting of three segments called sides. Any two sides intersect in exactly one point called a vertex. A triangle is named using the capital letters assigned to its vertices in a clockwise or counterclockwise direction. For example, the triangle below can be named triangle ABC in a To find the area of the triangle, you need to know its base and height. The base is the length of one side of the triangle, usually the side at the bottom. The height is the length of the line that connects the base to the opposite vertex, and makes a $\text{90}^ \circ$ angle with the base.
