Dilations - Scale Factor
Move the slider for the scale factor, k. When k is LESS than 1, what do you notice? When k is GREATER than 1, what do you notice?
Move point B to (2, 0) and adjust the scale factor, k, to 0.5, 1, 2 and 3. What do you notice about the scale factor and the coordinates of B'?
Leaving point A in its original position at (2, 3), move the center of dilation to (-1, 3), so that point A is 3 units RIGHT of the center of dilation. Then set the scale factor to 0.5, 1, 2 and 3. How far is A' from the center of dilation for each scale factor? How does this relate to the distance from the center of dilation to point A?
