Math Dilations | MathHelp.com

This lesson covers math dilations. Students learn that when the dimensions of a figure are increased or decreased to create a new figure that is similar to the original figure, the transformation is called a dilation. Students are then asked to determine whether a given transformation on a coordinate system represents a dilation. Students are also asked to graph a dilation of a given figure on a coordinate system by multiplying all of the coordinates of the vertices of the figure by a given number.
