Midterm Exam Review Unit 7: There are three ways to solve for a missing side length of a polygon when you are given a pair of similar polygons. Use any of the three methods we have just discussed. Similar Polygons and Triangle Similarity Shortcuts 10 minutes. There are three ways to solve for a missing side length of a polygon when you are given a pair of similar polygons. Solving Problems with Similar Polygons:

If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths. When groups of four have finished comparing their work, they may call me over to check their work against an answer key:. Discovering and Proving Circles Properties Unit If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths. Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons. One of my goals in this discussion is for students to be able to generalize their thinking to discover something new; for example, students will be able to explain why any two regular polygons with the same number of sides will be similar, using precise mathematical vocabulary.

## Similarity Problem Solving and Proofs

In this check for understandingmy students must first determine if the triangles are similar. Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons.

Now we will use the relationship between the sides of one polygon to find the lengths of the sides of the other polygons. When two shapes have the same shape but different sizes, we call the shapes similar. Similar Polygons 10 minutes.

Below are a few examples of polygons: Recall that a polygon is a closed shape consisting of a finite number of line segments that do not cross each other. Sign Up Log In. Toys cars and airplanes that are scaled down versions of the real objects.

There are three ways to solve for a missing side length of a polygon when you are given a pair of similar polygons. If you want the flag to be 2ft.

A large flag flown in front of a school is 4ft. Geometric Measurement and Dimension Unit Now we will have the same relationship between the other two sides: Use any of the three methods we have just discussed.

Solving Problems with Similar Polygons: If you want the flag to be 2ft. Now iin will sooving the relationship between the sides of one polygon to find the lengths of the sides of the other polygons.

Use similar polygons to solve problems. Similar Polygons and Triangle Similarity Shortcuts. Similar Polygons and Triangle Similarity Shortcuts 10 minutes. Set up a proportion to find problek missing side length.

In this section we will just concentrate on similar polygons. When groups of four have finished comparing their work, they may call me over to check their work against an answer key:. Explore the Polygons in GSP.

Discovering and Proving Triangle Properties Unit 8: One of my goals in this discussion is for students to be able to generalize their thinking to discover something new; for example, students will be able to explain why any two regular polygons with proble, same number of sides will be similar, using precise mathematical vocabulary.

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.

Polygonss sure that all of your units are the same in the ratios that you set up.

When groups of four have finished comparing their work, they may call me over to check their work against an answer key: Explore these similar polygonx in GSP see if the theorem holds: A large flag flown in front of a school is 4ft.

Triangle Similarity and Trigonometric Ratios Unit Like most warm-ups, I ask students to work individually before sharing out in their group to ensure that all students have had an opportunity to think on their own. Use any of the three methods we have just discussed. Recall that a polygon is a closed shape consisting of a finite number of line segments that do not cross each other.
