This video tutorial explains the differences between parallel and perpendicular lines. It begins with an introduction to lines and their properties, followed by a detailed explanation of parallel lines, which never intersect and are equidistant. The tutorial then covers intersecting lines and how they differ from perpendicular lines, which intersect at 90-degree angles. The video concludes with a summary of how to draw parallel and perpendicular lines using their properties.

What is a line?

• A path of points that ends at two points

• A path of points that forms a circle

• A path of points that goes on forever in one direction

• A path of points that goes on forever in two directions

What is a characteristic of parallel lines?

• They form a right angle

• They never intersect and are equidistant

• They are always curved

• They intersect at a point

What happens when two lines meet at a point?

• They form parallel lines

• They form intersecting lines

• They form a triangle

• They form a circle

What is a defining feature of perpendicular lines?

• They never meet

• They form a 45-degree angle

• They form a 90-degree angle

• They are always parallel

How can you determine if intersecting lines are perpendicular?

• By checking if they are equidistant

• By checking if they form a square corner

• By checking if they are parallel

• By checking if they are curved

What is a common misunderstanding about intersecting and perpendicular lines?

• All intersecting lines are perpendicular

• All parallel lines are intersecting

• All lines are perpendicular

• All perpendicular lines are intersecting

What angle do perpendicular lines form?

• 90 degrees

• 180 degrees

• 45 degrees

• 60 degrees

What should you look for to confirm lines are not perpendicular?

• Parallel lines

• A lack of a square corner

• A curved line

• A square corner
