Question

Which geometric concept is defined using the undefined terms point and line?

A) Angle
B) Circle
C) Parallel lines
D) Ray

Answer 1

The geometric concept defined using the undefined terms point and line is parallel lines.

Step-by-step explanation:

The geometric concept defined using the undefined terms point and line is C) Parallel lines. Parallel lines are two lines in a plane that never intersect, and they are defined as such using the undefined terms point and line. For example, in a coordinate plane, the lines y = 2x + 3 and y = 2x - 1 are parallel because they have the same slope of 2 and never intersect.
