Question

question 4 points 1
the common endpoint where the rays intersect is called the
______ of the angle.

○ vertex

○ side

○ ray

○ line segment

Explanation:

To solve this, we recall the definition of an angle. An angle is formed by two rays with a common endpoint. The common endpoint is called the vertex. "Side" refers to the rays themselves, "ray" is one of the components forming the angle, and "line segment" has two endpoints and is not the endpoint of the angle's rays. So the correct term is vertex.

Answer:

A. vertex
