Solution

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.
