Study Notes
Angles and Planes
- An angle is a figure formed by two rays sharing a common endpoint, which is called the vertex.
- The word 'angle' is derived from the Latin word 'angulus', meaning 'corner'.
- According to Euclid, a plane angle is the inclination of two lines to one another in a plane, which is formed by two lines that meet.
- Angles formed by the intersection of two planes are called dihedral angles.
- The measure of an angle is conventionally defined as the ratio of a circular arc length to its radius.
