a vertex or vertice(s)!
At a point, which is called a vertex.

< the point where the two rays meet is called a vertex.
The two rays that form an angle are called the "sides" of the angle. The point where the two rays meet is known as the "vertex" of the angle. Together, they define the space between the rays, which is measured in degrees or radians.
The vertex of the angle.
It's true, an angle is made up of two rays. Two rays meet at a point, and their relative position at the point where they meet will define an angle.

The point where light rays meet is called the focal point.
