Triangle

• A triangle is simple closed figure made up of three line segments.

• There are three angles in a triangle.

• The point of intersection of two adjacent sides of a triangle is called a vertex. There are 3 vertices in a triangle.

• A line segment joining a vertex to the mid- point of the side opposite to the vertex is called a median of the triangle.

• An altitude of a triangle is the perpendicular drawn from a vertex to the opposite side( produce if necessary).
