Segment BD is an altitude of triangle ABC. Find the area of the triangle. Triangle ABC with altitude BD is shown. Point A is at 2, 1. Point B is at negative 1, 4. Point C is at 2, 6. Point D is at 2, 4. 7.5 9.5 10 15.
Since the triangle is equilateral, it is also equiangular, and therefore the the angle at B is 60Â°. The height of a triangle is the straight line drawn from the vertex at right angles to the base. Therefore, triangle ADB is a 30-60-90 triangle.
