# 8.9.2. Equality of the Areas of Two Triangles

Given that

- A
- B
- C

### Example

Given that

### Solution

Draw

If two triangles share the same base and their vertices lie on a straight line parallel to the base, then the triangles are equal in area.

Triangles with congruent bases on one straight line that have a common vertex are equal in area. Therefore, the area of
