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 extended base is relevant in the context of an obtuse triangle: the altitudes from the acute angled vertices are exterior to the triangle and perpendicularly intersect the opposite base but not the base itself, and one of those altitudes can be treated as the height of the triangle in the above formula for its area.
