Copy of Parallel & Perpendicular Lines
PARALLEL LINES
The following applet demonstrates a property that parallel lines have when they're drawn in the coordinate plane.
Be sure to move the blue points around quite a bit!
QUESTION 1
Line a and Line b are parallel lines. Move the blue points around. What do you notice?
Define parallel lines in your own words.
PERPENDICULAR LINES
This applet demonstrates a property that perpendicular lines have when they're drawn in the coordinate plane.
Be sure to move the points around quite a bit and observe carefully as you do!
Line a and Line b are examples of perpendicular lines. What do you notice happens to both lines when you move the dots around?
What is a perpendicular line in your own words?
