G.3.1 Learning Goals

  • I can understand and apply the terms scale factor and dialtion.
  • I can dilate a figure given a scale factor and center.


Scale factor is the number by which every length in an original figure is multiplied when you make a scaled copy. A dilation with center P and positive scale factor k takes a point A along the ray PA to another point whose disctance is k times furthere away from P than A is.
