Does it matter how many points to dilate? The resource presents problems of dilating curved figures. Class members find out that not only do they need to dilate several points but the points need to be distributed about the entire curve to see the shape of the image. They also calculate the scale factor needed to reverse a dilation in this third installment of a 16-part series.
