Dilations

This video lesson introduces dilations. Dilations are a transformation that changes the size of a figure by enlarging it by a scale factor greater than one or by reducing it by a scale factor less than one. Real world examples are provided. Figures will be dilated about a center of dilation. Instruction is provided to learn to dilate in the coordinate plane with the origin as the center of dilation. Student practice is embedded with modeled exemplar problems.
