Dilation of Lines Exploration
Use the applet below to explore the properties of dilating a line on the coordinate plane.
Note that the center of dilation, point A, is on the line BC, but is not on the line DE. BOTH lines are dilated when the scale factor is increased in the applet below.
1. If the center of dilation is ON the line, how does the dilated line compare with the original line?
2. If the center of dilation is NOT on the line, how does the dilated line compare with the original line?
