Question

In a ΔABC, right-angled at A, it is given that AB = AC, ∠C is equal to ______.

विकल्प

• 30°

• 45°

• 60°

• 90°

Answer 1

In a ΔABC, right-angled at A, it is given that AB = AC, ∠C is equal to 45°.

Explanation:

Since ΔABC is right-angled at A, angles B and C add to 90°.

AB = AC means the sides opposite angles C and B are equal, so angles B and C are equal.

Two equal angles that sum to 90° must each be 45°.
