Enlargements with Fractional Scale Factors

This Enlargements with Fractional Scale Factors video also includes:

Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal and vertical distances. By working around the figure, one vertex at a time, the transformed figure is mapped out.
