Answer 1

It's ST.

Answer 2

When you name a ray, the first point used must be the endpoint of the ray.
The second point can be any point on the line that includes the ray, as long as the pont is on the correct side showing the direction of the ray.

Answer 3

First it's helpful to remind ourselves what a ray is.
It is a part of a line. It starts at one point and goes forever only in one direction.

Answer 4

What point shown in the figure does this ray start at?
