1. The other name for the endpoint of the a ray is letter "A. terminal point" as terminal means end. The initial point is the starting point of the ray. The vertex is for the angle where the two rays intersect. 

2. The answer to this question is letter "C. 2". We only need to define the starting point and the terminal point. 

Answer:

1)Another name for the endpoint of a ray is initial point.

2)1 point only .

Step-by-step explanation:

Given  : ray.

To find :  another name for the endpoint of a ray and how many points are needed to define a ray.

Solution : We have given ray

Ray : A ray is a part of a line that has one endpoint and goes on infinitely in only one direction.

Example : ·→→→→ sun ray .

Another name for the endpoint of a ray is initial point.

and we need to define only one point to define ray that is only starting point.

Therefore, 1)Another name for the endpoint of a ray is initial point.

2)1 point only .
