An angle is defined as the figure formed by two lines diverging from a common point.
Angles are measured in degrees, with a full circle being 360 degrees.
There are three basic types of angles: right angles, acute angles, and obtuse angles.
1) A right angle is an angle that measures exactly 90 degrees.
2) An acute angle is an angle that measures less than 90 degrees.
3) An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.
