An angle is a fraction of a circle measured in degrees. A whole circle is 360 degrees. There are four types of basic angles students in elementary school study in geometry. They are as follows.

Acute: an angle whose measure is less than 90 degrees. Right: an angle whose measure is exactly 90 degrees. Obtuse: an angle whose measure is bigger than 90 degrees but less than 180 degrees. Straight: an angle whose measure is 180 degrees. ## Classify angles
