How to explain parallel and perpendicular lines in lines to your child: Example question
31 October 2026
Understanding parallel and perpendicular lines can help your child spot patterns and shapes in everyday objects. This simple example question will guide you both through what these lines look like and how to draw them.
Example question
Draw two lines that are parallel and two lines that are perpendicular.
Step 1: Draw the first line.
Draw a straight line from left to right.
Step 2: Draw a second line parallel to the first.
Draw another straight line above or below the first line. Make sure it never meets the first line, no matter how far you extend them.
Step 3: Draw a third line crossing the first line at a right angle.
Draw a line that meets the first line and forms a perfect corner (a right angle).
Step 4: Draw a fourth line crossing the third line at a right angle.
Draw a line that meets the third line and also forms a right angle.
Answer:
The first two lines are parallel because they never meet and are always the same distance apart.
The third and fourth lines are perpendicular because they cross each other at right angles (90 degrees).
Key insight: After working through this example, your child should be able to recognise and name parallel and perpendicular lines in pictures and diagrams. There are more practice questions on parallel and perpendicular lines ready for your child to try next.
