Understanding Parallel and Perpendicular Lines

What is the main feature of parallel lines on a graph?

• They have the same gradient.

• They intersect at 90 degrees.

• They curve towards each other.

• They have different steepness.

Which of the following is true about parallel lines?

• They eventually cross each other.

• They have different gradients.

• They go in the same direction.

• They form a triangle.

What is the significance of the gradient in parallel lines?

• It determines their color.

• It keeps them parallel.

• It changes their length.

• It makes them intersect.

How do perpendicular lines interact on a graph?

• They cross at 90 degrees.

• They run parallel to each other.

• They never meet.

• They have the same gradient.

Where can you commonly find perpendicular lines in real life?

• In a spiral staircase.

• On a curved road.

• In a car park.

• On a circular track.

What is the relationship between the gradients of perpendicular lines?

• They are equal.

• They are infinite.

• They are both zero.

• They are different.

What will be discussed in future videos according to the conclusion?

• The history of lines.

• The shapes of polygons.

• The types of angles.

• The concept of gradients.
