Here are two similar polygons.Measure the side lengths and angles of each polygon. What do you notice?[img]https://cdn.openupresources.org/uploads/pictures/8/8.2.B.PP.Image.02.png[/img]

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.[img]https://cdn.openupresources.org/uploads/pictures/8/8.2.B.PP.Image.05.png[/img][img]https://cdn.openupresources.org/uploads/pictures/8/8.2.B.PP.Image.06.1.png[/img]
