Question

Which of the following figures has only one pair of parallel lines?

• A. The pink figure
  
• B. The purple figure
  
• C. The green figure
  
• D. The yellow figure
  

Answer 1

The correct option is C The green figure


We know that parallel sides are two lines that go in the same direction but never cross each other.
The purple, pink, and yellow figures have two pairs of parallel lines, i.e., side AB is parallel to side DC and side AD is parallel to side BC.
In the green figure, sides AB and DC are parallel.
But sides AD and BC are not parallel as they do not go in the same direction.
Hence, the given shape has only one pair of parallel lines.
