Question

A geometry teacher asked Radric to define "parallel lines." Radric said that parallel lines are lines in a plane that do not have any points in common. Is Radric's definition valid?

Answer 1

Answer:

Radric answer is Right.

Step-by-step explanation:

• Radric said that the parallel lines are the lines in a plane that do not have any points in common.

• He is right as he is talking about the lines in a plane i.e the line are not intersecting each other even till infinity .

• It is not possible for two non-parallel lines not intersect each other in a plane at any point. Even, if there is a small deviation in the two lines they will intersect at some point in the plane.

So the Radric is right and his answer is valid.  

Answer 2

Answer: The answer is Yes.

Step-by-step explanation:  Given in the question that Radric was asked to define "parallel lines" and he said that parallel lines are lines in a plane that do not have any points in common. We are to decide whether Radric's definition is valid or not.

Parallel lines are defined as lines in a plane which never meets or any two lines in a plane which do not intersect each other at any point are called parallel.

Thus, Radric's definition is valid.
