Pocket Mathematics just received an update with new chapter: Angles - basic principles.
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces.
New chapter, Angles - basic principles, contains the following sections:
- Designation of angles
- Flat angle
- Degree measure of an angle
- Arc measure of an angle
- Grade measure of an angle
- Directed angle
- Multihedral angle
