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!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!*What can you conclude about parallel lines drawn in the coordinate plane?

What can you conclude about perpendicular lines that are drawn in the coordinate plane? (Assume the lines are not aligned horizontally and vertically).
