What is the definition of a ray in geometry?

Back

A ray is a part of a line that starts at a point and extends infinitely in one direction.

What does it mean for point B to be the midpoint of segment AC?

Back

Point B is the midpoint of segment AC if it divides the segment into two equal parts, meaning AB = BC.
