Which pair of undefined terms is used to define the term parallel lines?

A. Point and line

B. Plane and line

C. Point and ray

D. Ray and line

A

Answer: A. Point and line

Two lines are said to be parallel to each other when they do not intersect themselves at any point. In other words, parallel lines will continue to move in a single straight direction without meeting at any point; they are equidistant from one another. So line and point are terms used to explain the term “parallel lines.” Both of these terms are undefined in geometry.
