Corresponding Parts of Similar Triangles

Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then match the corresponding parts of similar triangles. They'll produce reductions, enlargements, and congruent figures, as well as compare corresponding angles.
