The measure of an acute angle is more than 90 degrees, less than 90 degrees, or 90 degrees.

This is a right angle. The measure of this angle is 90 degrees. This helps us to eliminate one of our possible answers. An acute angle is not 90 degrees. A right angle measures 90 degrees. An angle which measures less than 90 degrees is called an acute angle. And an angle which measures more than 90 degrees is called an obtuse angle. So, we can say the measure of an acute angle is less than 90 degrees.

Acute angles measure less than 90 degrees, right angles measure 90 degrees, and obtuse angles measure more than 90 degrees and less than 180 degrees. The measure of an acute angle is less than 90 degrees.
