Area of Triangles with same base and same height

Triangles with same base and height Observe the relationships between two triangles that share the same base and have same height with respect to the base. The diagram shows two triangles, Triangle ABD and Triangle ABE. Note that these triangles have the same base, AB. Information already given:
  • Area of each triangle [list]
  • Height of each triangle with respect to the base AB
1) Move either point D or point E to the left or to the right 2) What observations can you make?
