If △\triangleABC ≅\congPQR, and ∠\angleC = 80°, ∠\angleA = 10°, then what will be the measure of ∠\angleQ?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 90°.

According to the given question,

 △\triangleABC ≅\congPQR, then 

∠\angleA = ∠\angleP, ∠\angleB = ∠\angleQ and ∠\angleC = ∠\angleR

In triangle ABC, ∠\angleA + ∠\angleB + ∠\angleC = 180°

⇒ 10° + ∠\angleB + 80° = 180°

⇒ ∠\angleB = 180° - 90°

⇒ ∠\angleB = 90°

So, ∠\angleQ = ∠\angleB = 90°
