Final answer:
To prove that the triangles APQR and ATSR are similar, you need to show that corresponding angles are equal and that the triangles have two pairs of equal angles. d) ΔAPQ ~ ΔATS by angle-angle similarity.
Step-by-step explanation:
To prove that APQR ~ ATSR, we need to show that ∠A = ∠A, ∠P = ∠S, ∠Q = ∠T, and ΔAPQ ~ ΔATS.
Since QR || PT and QPR = ZSTR (corresponding angles are equal), we have ∠A = ∠A and ∠P = ∠S (corresponding angles are equal).
Also, since QR || PT, we have ∠Q = ∠T (corresponding angles are equal).
Finally, ΔAPQ ~ ΔATS by angle-angle similarity.
