An angle was described by Euclid as "the inclination to one another of two lines which meet each other in the same plane." An angle is a bend formed by two intersecting lines or line segments.
Angles are described as being:
- acute (less than 90 degrees)
- right (90 degrees exactly)
- obtuse (greater than 90 degrees but less than 180 degrees)
- reflex (over 180 degrees)
A 180 degree angle is a straight line.
