Step 1
Step 1: Given that ∠R ≅ ∠B, ∠I ≅ ∠A, and ∠T ≅ ∠C, we can conclude that △TRI is congruent to △ABC by the Angle-Angle-Angle (AAA) postulate. Show more…

By one-to-one correspondence, DEF is equivalent to RST. Segment DE is congruent to segment RS, and segment DF is congruent to segment RT. Angle D is congruent to angle R. By which test can we determine that the two triangles are congruent?
