Question

In the following figure ABCD, the acute angles are .

• A. ∠A and ∠C
• B. ∠B and ∠A
• C. ∠C and ∠D
• D. ∠D and ∠B

Answer 1

The correct option is A ∠A and ∠C

The angle with measures less than 90° is known as acute angle.

The angle with measure more than 90° but less than 180° is known as obtuse angle.

Here from the figure ABCD, we can observe:


Values of ∠A and ∠C are both less than 90°.
∠B and ∠D value more than 90° but less than 180°.

∴ ∠A and ∠C are the acute angles in the figure.
