Question

Please tell me this answer...​

Answer 1

☆Given:-

• The sum of lengths of any two sides is greater than third side in a triangle.

☆To Find :-

• Is the sum of any angles of a triangle is also greater than third angle.

☆Solution:-

• Let we consider right angled ABC, where ∠B= 90°, ∠A= 30°, ∠C= 60°.
• Here, sum of any two angles is not always greater than third angle .
• For e.g= ∠A+ ∠C is not greater than ∠B.

Hence, Sum of any angle of a triangle is not always greater than third angle.

Answer 2

Answer:

Given:-
