question 1 of 10

b. any two rays
c. two rays that share the same endpoint
d. any ray and any line

By definition, an angle is formed by two rays that share the same endpoint, called the vertex of the angle. Parallel lines do not form an angle, any two non - related rays don't necessarily form an angle, and a ray and a line in general position don't form an angle in the standard sense.

Answer:

C. two rays that share the same endpoint
