Question

has only one pair of parallel lines.

• A. Figure 1
• B. Figure 2
• C. Figure 3
• D. Figure 4

Answer 1

The correct option is B Figure 2

Parallel lines never intersect, no matter how much they are extended.

So let's extend the lines of the given figures to identify which figure has only one pair of parallel lines.


Figure 1 has no pair of parallel lines.
All the lines are intersecting with each other.
Hence, this is not the correct option.


Figure 2 has one pair of paralle lines and one pair of intersecting lines.
Hence, this is the correct option.


In Figure 3, both the opposite pair of lines are parellel.
Since we need just one pair of parallel lines, this is not the correct option.

In Figure 4 also, both the opposite sides are parallel.
Hence, this is also not the correct option.

Therefore, Figure 2 is the correct option.
