In this worksheet, you will be able to explore the relationship between the slopes of Perpendicular Lines.
Use the and the sliders to change the slope of the line. What is the rise and run of the original line? Is the slope positive or negative? What is the rise and run of the perpendicular line? Is the slope positive or negative? What do you get when you multiply the slope of the original with the slope of the perpendicular? How does the slope of the original and the slope of the perpendicular relate?
