Lines are everywhere!
Without parallel and perpendicular lines, we wouldn't have the shapes that make up everyday life.
But what exactly is the difference between perpendicular and parallel lines?
👉 Time to find out!
Parallel Lines
These are lines that never touch and are equidistant from each other.
They can be straight or curved.
Straight parallel lines
Curved parallel lines
⭐ Spot the parallel lines
Look at these real life examples:

Which picture is an example of parallel lines?
Perpendicular Lines
These are lines that cross over with each other at right angles.
The two lines intersect each other at a right angle (or 90°).
⭐ Spot the perpendicular lines
