Q. 2 C4.8( 4 Votes )

In a triangle ABC, B = C = 45°, then the triangle is ______
A. right triangle

B. acute angled triangle

C. obtuse angle triangle

D. equilateral triangle

Answer :

Given that B = C = 45°


We know that the sum of the angles of a triangle is 180°.


⇒ ∠A + B + C = 180°


⇒ ∠A = 180° - 45° - 45°


⇒ ∠A = 90°


Hence, ∆ABC is a right triangle.
