2 rays
two rays make up an angle, so the rays are the sides of the angle.
There are three ways to name an angle, provided there are only three points on the angle. Say the vertex is point A, and there are two rays extending. Each has another point on it, points B and C. You can name this angle BAC, CAB, or A.
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 vertex is the point where two rays begin and form and angle
