What defines an acute angle?

Explanation:
An acute angle is an angle whose measure is greater than zero and less than 90 degrees. It appears as a sharp turn, smaller than a right angle. Because a right angle is exactly 90 degrees, anything less than that is acute, while anything 90 degrees or more falls into other categories. Angles of 90 degrees are right angles; angles between 90 and 180 degrees are obtuse; 180 degrees is a straight angle; and 360 degrees is a full rotation. So examples like 30°, 45°, and 60° all fit as acute angles.
