Question

I am confused, can someone help?

Answer 1

i would go with the second one because it says they meet at a common vertex(point) and that’s the better definition

Answer 2

the figure made of two Ray's with a common vertex

Explanation:

An angle is formed when two rays share a common endpoint. That common endpoint is called the vertex and the two rays are called the sides of the angle.

the first one the answer is vertex.

the last one is just simply not it.
