Define the terms: line, line segment, ray, and point.

Here are the definitions for the geometric terms:

i) Line
A line is a straight path that extends infinitely in two opposite directions and has no thickness. It is typically represented by an arrow on each end.

ii) Line segment
A line segment is a part of a line that has two distinct endpoints. It has a definite length.

iii) Ray
A ray is a part of a line that has one endpoint and extends infinitely in one direction. It is represented by an arrow on one end.

iv) Point
A point is a location in space, represented by a dot, and has no dimension (no length, width, or height).
