# Area of a triangle (related to the two of its altitudes)

## Description

Altitude of a triangle is a straight line through a vertex and perpendicular to a line containing the base (the opposite side of the triangle). The area of the triangle can be calculated by the two of its altitudes and the sine an angle.
