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 ninety degrees), right angles (ninety degrees exactly), obtuse (greater than ninety degrees but less than one hundred eighty degrees), and reflex (over 180 degrees). A one-hundred-eighty degree angle is a straight line.
