Dilating a quadrilateral
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 to change the shape of the quadrilateral.
Move the center point E to dilate from a different location.
Use the slider to change the scale factor.
To understand how dilation produces similar figures, see Dilating a triangle on GeoGebraTube: http://ggbtu.be/m2742017
