two rays make up the side of an angle

help_people · Answer

An angle is a figure consisting of two non-collinear rays with a common endpoint. Remember that angles are named with the vertex in the middle of two letters or by just naming the vertex. For example, ∠ABC or ∠B.

Sorry. I am having computer problems.

Is the word "line" in the definition of angle in your book?

directrix · Answer

Look in your book and see if the three undefined terms are point, line, and plane.

If they are, the best choice of answer, I think, would be point.

The word "endpoint" is part of the angle definition. Think of it as end point.
