# In a triangle ABC, ∠B = ∠C = 45°, then the triangle is ______A. right triangleB. acute angled triangleC. obtuse angle triangleD. equilateral triangle

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.
