Question

Which pair of lines will intersect at only one point?

• A. Coincident lines
• B. Parallel lines
• C. Intersecting lines

Answer 1

The correct option is C Intersecting lines

Let's discuss all the options one by one:
$\underset{–}{\text{Coincident Lines:}}$
Lines that have infinite points of intersection or coincide with each other are called coincident lines.

In above figure, two lines coincide one over the other and hence they have infinite point of intersection.

$\underset{–}{\text{Parallel Lines:}}$
Lines that do not intersect or are in same direction are known as parallel lines. As depicted in picture below,
Therefore, parallel line have no point of intersection.

$\underset{–}{\text{Intersecting Lines:}}$
Lines that cross each other at one point are known as intersecting lines. As depicted in below figure,
Therefore, intersecting lines intersect at only one point.
Hence, (c) is the correct option
