Parallel & Perpendicular Lines

This video tutorial introduces the concepts of parallel and perpendicular lines, explaining their characteristics and how they appear on a graph. Parallel lines have the same gradient and never intersect, while perpendicular lines intersect at 90 degrees and have different gradients. The video uses real-world examples to illustrate these concepts and hints at future lessons on gradients.

What is the significance of the gradient in understanding parallel and perpendicular lines?

Can you provide examples of where perpendicular lines can be found in everyday life?
