Answer:
Step-by-step explanation:
The vertical angles at A are the same. The angles at B and F are marked the same. So each triangle has two angles in common with the other. That is all that is required for AA similarity.
Vertex A corresponds to itself, vertex A.
Vertex B corresponds to vertex F, since that is where the angles are marked the same.
The remaining vertices are C and G, and they correspond to each other.
Hence, the corresponding vertices (in the same order) are ... ABC and AFG. This is how the similar triangles are named:
ΔABC ~ ΔAFG
