Question 3 of 20

4. Choose the correct statement

If angles forming a linear pair are equal, then each of these angles measures 90°.

Angles forming a linear pair can both be acute angles.

If two adjacent angles are equal, then each angle measures 90°.

Two angles whose sum is 90° are called supplementary angles.
