Answer: The correct answer is choice A.
Explanation:
This is because the triangles have the same angles, but are scaled differently. Thus because of the scale, there can be no correlation between the sides. Because the triangles share point E you can see that both triangles share the same angle but also notice how lines CD and AB are parallel. This makes all angles identical proving the triangles are the same but different sizes. Concluding that choice A is correct.
