The two rays that make up an angle are called what?

Explanation:
The sides of an angle are the two rays that form it. They share a common endpoint, which is the vertex. So the term that names the rays themselves is sides. A vertex is the point where the rays meet, not the rays themselves. Edges are usually used for the boundaries of polygons, and while someone might hear “arms” in everyday language, the precise math term for the rays is sides.
