An angle is a figure formed by two rays that have a common endpoint. Angles can be classified in several ways, including acute, right, obtuse, straight, and reflex.
An acute angle is an angle that measures less than 90 degrees.
A right angle is an angle that measures exactly 90 degrees.
An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.
A straight angle is an angle that measures exactly 180 degrees.
A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees.
