Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and have the same slope.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if they intersect at a right angle (90°) and their slopes are negative reciprocals.

Front

What is the formula for the perimeter of a rectangle?

Back
