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.
- Lead a discussion on whether all fractional scale factors make the figure smaller
- Scholars should know how to do basic enlargements
- Practice sheets contain concepts from other videos
- Uses an example with the origin as the center
- Explains how to use the ray method with fractional scale factors
