Lesson 11: Practice Problems
Problem 1
Each diagram has a pair of figures, one larger than the other. For each pair, 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.
Problem 2
Here are two similar polygons.
Measure the side lengths and angles of each polygon. What do you notice?

Problem 3
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.
Problem 4
Describe a sequence of translations, rotations, and reflections that takes Polygon

Problem 5 From Unit 1 Lesson 2
Draw the translated image of
so that vertex moves to . Tracing paper may be useful. Draw the reflected image of Pentagon
with line of reflection . Tracing paper may be useful. Draw the rotation of Pentagon
around clockwise by an angle of 150 degrees. Tracing paper and a protractor may be useful.
