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.
Given the coordinates of the vertices A, B, and C as shown in Figure 2a we can compute the lengths of the sides a, b, and c and then apply Heron's formula to compute the area of the triangle ABC.
