### 7-2 PROBLEM SOLVING RATIOS IN SIMILAR POLYGONS ANSWERS

Now we will use the relationship between the sides of one polygon to find the lengths of the sides of the other polygons. Given that two polygons are similar, there is a scale factor between the corresponding sides of the polygons, call the scale factor, k. Unit 12 Unit 1: Discovering and Proving Circles Properties Unit Make sure that all of your units are the same in the ratios that you set up. We know that a proportion is two ratios that are equal to each other, so you can use either ratio, the relative size or the scale factor, and find the missing side.

A large flag flown in front of a school is 4ft. Applications Using Similar Polygons: Dilation and Similarity Unit Test. Applications Using Similar Polygons: Similar Polygons and Triangle Similarity Shortcuts 10 minutes. Recall that two shapes are congruent if they have the same shape and size.

You can also think of similar objects or shapes as scaled versions of each other.

Unit 12 Unit 1: In this section we will just concentrate on similar polygons. Toys cars and airplanes that are scaled down versions of the real objects.

In this section we will just concentrate on similar polygons. Midterm Exam Review Unit 7: Click here to measure the side IK.

## Similarity Problem Solving and Proofs

Below are a few examples of polygons: Make sure that all of your units are the same in the ratios that you set up. Discovering and Proving Angle Relationships Unit 5: Now we will use the relationship between the sides of one polygon to find the lengths of the sides of the other polygons. Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons.

Similar Polygons and Triangle Similarity Shortcuts. Set up a proportion to find the missing side length. Then they need to justify how they know before solving for mone of the side lengths.

Sign Up Log In. When groups of four have finished comparing their work, they may call me over to check their work against an answer key: Check the angles and corresponding sides: Recall that two siimilar are congruent if they have the same shape and size. If you want the flag to be 2ft. As students share out in their groups, I circulate the room, taking note of the diagrams students have drawn to get a sense of their arguments.

ratioa Explore these similar polygons in GSP see if the theorem holds: We can use the relationship between two of the corresponding sides, to find the rest of the corresponding sides. Make sure that all of your units are the same in the ratios that you set up. When two shapes have the same shape but different sizes, we call the shapes similar.

Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons. When two shapes have the same shape but different sizes, we call the shapes similar. Below are a few examples aanswers polygons: Explore the Polygons in GSP. Similar Polygons 10 minutes.

Use similar polygons to solve problems. If two polygons are similar, then the ratio of the lengths of the two corresponding sides is the scale factor.

Introducing Geometry Unit 3: Nikki Masson and Brook Buckelew. If you want the flag to be 2ft. Toys cars and airplanes that are scaled down versions of the real objects.
