More about triangles :

• A triangle is a closed polygon made up of three line segments .

• It has three sides , three vertices and three angles .

• The sum of all the angles inside the triangle is 180° .

• The sum of all angles exterior to triangle is 180° .

• The perpendicular height of a triangle is called its altitude .

• The median is the line segment that originates from a vertex and cuts the opposite line segment into half .
