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. Label any new points. Problem 1 For each pair of points, find the slope of the line that passes through both points. More Geometry Lessons Transformation Games In these lessons, we will learn what is dilation or enlargement and reduction? Measure the longest side of each of the three triangles.

Problem 5 from Unit 1, Lesson 14 The diagram shows two intersecting lines. If yes, what are the center of dilation and the scale factor? These two triangles are similar. Describe a sequence of translations, rotations, and reflections that takes Polygon P to Polygon Q. Problem 3 The two triangles shown are similar.

What do you notice? Problem 3 Consider the graphed line.

You can use the free Mathway calculator and problem solver below to practice Algebra or other math topics. Measure the longest side of each of the three triangles. The straight line is drawn from a fixed point called the center of dilation.

## Unit 2: Practice Problem Sets

Please submit your feedback or enquiries via our Feedback page. Measure the side lengths and angles of lewson polygon. Do you think two equilateral triangles will be similar alwayssometimesor never? Problem 3 Here is a triangle. Enlarge triangle PQR with O as the center of enlargement and scale factor. Problem 4 These two triangles are similar.

Scroll down the page for more examples and explanations of dilations. Are the two triangles similar? Problem 3 Make a perspective drawing.

For filations 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. Explain why they are similar.

Problem 3 Here are three polygons. Problem 1 These two triangles are similar. The distance the points move depends on the scale factor. Find the measures of the following angles.

The diagram shows two nested triangles that share a vertex. More Geometry Lessons Transformation Games In these lessons, we will learn what is dilation or enlargement and reduction? Measure the side lengths and angles of your triangles. For each pair of points, find the slope of the line that passes through both points. Problem 1 Each diagram has a pair of figures, one larger than the other.

Label any new points. Problem 2 Draw two equilateral triangles that are not congruent. Explain why they are not similar.

These two triangles are similar. Problem 3 from Unit 1, Lesson 12 Describe a rigid transformation that you could use to show the polygons are congruent. dilationa

Problem 2 Here are two similar polygons. Explain how you know. Describe a sequence of translations, rotations, and reflections that takes Polygon Solvinng to Polygon Q. 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.
