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.
The area of ABC is 40. The trick is that the SAT folks would like you to say, the area of ADE must be one half of 40, or 20. But you are smart enough to know that area is based on squares, so the area of a triangle with sides half as long must be the area x 1/2 squared, or in this case 40 x 1/4 = 10.
