Parallel and Perpendicular Lines Quiz

What are parallel lines?

• Lines that intersect at a right angle

• Lines that never intersect

• Lines that intersect at a 90-degree angle

• Lines that intersect at a 45-degree angle

How can you determine if two lines are parallel?

• By comparing their x-intercepts

• By comparing their y-intercepts

• By comparing their slopes

• By comparing their equations

What is the condition for two lines to be perpendicular?

• Their slopes are the same

• Their slopes are negative reciprocals

• Their y-intercepts are the same

• Their x-intercepts are the same
