In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles.
An angle is a measure of rotation around a point. It is formed by two rays that have a common endpoint, called the vertex of the angle. The rays are called the sides of the angle. The size of an angle is usually measured in degrees or radians.
For example, consider two rays that start at the vertex and extend out in different directions. If we rotate one of the rays about the vertex, the angle between the rays will change. If we complete a full rotation, the angle will be 360 degrees. If we rotate less than a full rotation, the angle will be less than 360 degrees.
Angles are used in geometry to describe the shape and size of figures and to describe the relationships between lines and curves. They are also used in trigonometry to solve problems involving lengths and angles of triangles.
