Question

Given:AC – AR<1 = <2Prove:<3 =<4​

Answer 1

Answer:

ΔCTA ≅ ΔDRA

Step-by-step explanation:

Triangles CTA and DRA are congruent by ASA postulate. This is because:

• ∠1 ≅ ∠2 (given)

• AC ≅ AR (given)

• ∠A is the same for both triangles (they are opposite angles)

Then, correspondent angles and sides are congruent, for example, ∠3 ≅ ∠4
