An angle.
They are three concurrent rays.
An angle is formed by two rays with the same endpoint. If the two rays are perpendicular to one another, they form a right angle.
Two rays with the same endpoint form an angle. A ray is a part of a line that starts at a particular point and extends infinitely in one direction. When two rays share the same endpoint, they create an angle that is measured by the amount of rotation from one ray to the other. The common endpoint is called the vertex of the angle.
Opposite rays are rays that share the same endpoint (have a common endpoint), but they also form a line.Not always.
