What figure is comprised of two rays that share a common endpoint called a vertex?

a. ray
b. angle
c. line segment
d. point

That's called an angle

rays have 1 endpoint and extend infinitley in a direction

so the answer isn't A
the answer is B because there is a vertex

it isn't C because that would just be 2 rays that share 2 common points

it isn't D because not

answer is B, angle

The pie is multyplued by the second step
