Question

Define the following (a)parallel line (b) radius of a cicle​

Answer 1

Answer:

parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. ... A line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are also said to be parallel.

RADIUS OF A CIRCLE - straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter. the length of such a line.

hope this helps ... kindly rate me as a brainiest answer..... thanks
