Answer:
AA Similarty
Step-by-step explanation: We are given that two angles are congruent so we use AA SImilarity. Stating that if two angles are congruent, then the figures are similar.
The postulate that can be used to prove that triangles ABC and DEF are similar triangles is: C. AA Similarity Postulate.
What is the AA Similarity Postulate?
The AA similarity postulate states that when two triangles have two pairs of corresponding angles that are congruent to each other, the two triangles are regarded as similar triangles.
Thus, triangles ABC and DEF have:
two pairs of congruent angles - ∠B ≅ ∠E and ∠C ≅ ∠F.
Therefore, the postulate that can be used to prove that triangles ABC and DEF are similar triangles is: C. AA Similarity Postulate.
