समद्विबाहु त्रिभुज में दो बराबर कोण 50° हैं तो तीसरा कोण कितना होगा?

A) 60° / 60° B) 70° / 70° C) 80° / 80° D) 100° / 100°
Show answer and explanation
Correct Answer

C. 80° / 80°

Explanation

The angle sum of a triangle is 180° so the third angle is 180° - 100° = 80°.

त्रिभुज के कोणों का योग 180° है इसलिए तीसरा कोण 180° - 100° = 80° है।
