11.1 Similar Polygons

We are looking at similar polygons this chapter. We start out by looking at what makes polygons similar. Then we make a distinction between how the word similar is used in English and math classes.

We looked at how making a shape bigger or smaller, but keeping the "shape" the same results in a similar shape.

The projector served as a good example for this.
