two rays make up an angle, so the rays are the sides of the angle.
The angle that is formed by the opposite rays is called the straight angle. This is from the fact that the opposite rays form a straight line.
The angle is called the reflected angle.
is called a straight angle
In planar 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.
The two rays that form an angle are called the legs or sides of the angle. The meeting point of the two rays that form an angle is called the vertex.
An angle consists of two rays called sides with a common endpoint called the vertex.
