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 term used to describe the steepness of a line on a graph?

• Angle

• Slope

• Gradient

• Direction

Which of the following is true about parallel lines?

• They have different gradients.

• They change direction frequently.

• They never cross each other.

• They intersect at 90 degrees.

How do perpendicular lines interact on a graph?

• They never meet.

• They have the same gradient.

• They run parallel to each other.

• They intersect at 90 degrees.

Where can you commonly find perpendicular lines in real life?

• On a curved road

• In a circular park

• On a football pitch

• In a spiral staircase

What is a key difference between parallel and perpendicular lines?

• Perpendicular lines intersect at 90 degrees.

• Parallel lines always intersect.

• Perpendicular lines never intersect.
