IM 8.2.6 Practice: Similarity

The diagram has a pair of figures, one larger than the other. Show that the two figures are similar by identifying a sequence of translations, rotations, reflections, and dilations that takes the smaller figure to the larger one.
Describe the sequence of transformations you performed to take the smaller figure to the larger figure.

Here are two similar polygons. Measure the side lengths and angles of each polygon.
What do you notice?
Each figure shows a pair of similar triangles, one contained in the other. For each pair, describe a point and a scale factor to use for a dilation moving the larger triangle to the smaller one. Use a measurement tool to find the scale factor.
What point did you use for the center? What is the scale factor for moving the larger triangle to the smaller one?
