Example 2:Using the picture above, change the scale factor to^13. FindQ′′.
Solution:Now the scale factor is^13 , soQ′′is going to be^13 the distance away fromPasQis. In other words,Q′′is
going to be 6×^13 =2 units away fromP.Q′′will also be collinear withQand center.
Example 3:KLMNis a rectangle with length 12 and width 8. If the center of dilation isKwith a scale factor of 2,
drawK′L′M′N′.
Solution:IfKis the center of dilation, thenKandK′will be the same point. From there,L′will be 8 units aboveL
andN′will be 12 units to the right ofN.
