# Dilating a pentagon

Dilation is a technique for creating similar figures.
Each point is stretched outwards from the center point D by multiplying distances by the scale factor. (Outwards if the scale factor is bigger than 1.)
Move the points A, B, C, D, E to change the shape of the pentagon.
Move the center point F to dilate from a different location.
Use the slider to change the scale factor.
