Types of Angles! A right angle: Right angles ALWAYS measure 90 degrees and look like a perfect corner. A straight angle: Straight angles ALWAYS measure 180 degrees and are a straight line. An acute angle. Acute angles ALWAYS measure less than 90 degrees. An obtuse angle: Obtuse angles ALWAYS measure more than 90 degrees, but less than 180 degrees. There are four different types of angles. These are: acute angles, obtuse angles, right angles, and straight angles. Right angles always measure 90
