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 .
