Match the following

• Scale Factor

• Dilation

• Rigid Transformations

• The origin is often used as the center of dilation. If you are dilating a figure centered at the origin, you can multiply the coordinates of the points in the preimage by the scale factor to determine the points in the image

• Non-Rigid Transformations

• Translation, Reflection, Rotation

• Dilation

• The factor by which every length in

  the pre-image is increased or decreased when

  you make a scaled copy

• Center of origin

• The process of resizing an object by a certain scale factor
