# 7-2 PROBLEM SOLVING RATIOS IN SIMILAR POLYGONS ANSWERS

Set up a proportion to find the missing side length. When two shapes have the same shape but different sizes, we call the shapes similar. If you want the flag to be 2ft. 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. When groups of four have finished comparing their work, they may call me over to check their work against an answer key: Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons. Suppose you want to make a scaled down version of the flag. Discovering and Proving Circles Properties Unit Discovering and Proving Triangle Properties Unit 8: Students will be able to apply the definition of similarity to determine whether polygons, triangles in particular, are similar and solve for sides and angles when possible.

Polygons whose corresponding angles are congruent and whose corresponding sides are proportional are called similar polygons. Discovering and Proving Angle Relationships Unit 5: A large flag flown in front of a school is 4ft.

Then they need to justify how they know before solving for mone of the side lengths. Similar Polygons and Triangle Similarity Shortcuts.

Dilation and Similarity Unit Test. Applications Using Similar Polygons: Given that two polygons are similar, there is a scale factor between the corresponding sides of the polygons, call the scale factor, k. The Soda Can Task: You can also think of similar objects or shapes as scaled versions of each other. Check the angles and corresponding sides: Toys cars and airplanes that are scaled down versions of the real objects.

Set up a proportion to find the missing side length. Introducing Geometry Unit 3: You can also think of similar objects or shapes as scaled versions of each other.

Big Idea Students will deepen their understanding of triangle similarity by solving similarity problems and writing proofs.

## Similarity Problem Solving and Proofs

If two polygons are similar, then the ratio of the lengths of the two corresponding sides is the scale factor. If you want the flag to be 2ft. To keep the conversation growing, I will ask pairs to then compare their thinking as a group of four with their table partners. Sign Up Log In. If two polygons are similar, then the ratio of the lengths of the two corresponding sides is the scale factor.

A large flag flown in front of a school is 4ft. Recall that solvig shapes are congruent if they have the same shape and size. Midterm Exam Review Unit 7: Recall that a polygon is a closed shape consisting of a finite number of line segments that do not cross each other.

Recall that a polygon is a closed shape consisting of a finite number of line segments that do not cross each other. Click here to measure the side IK.

Check the angles and corresponding sides: Suppose you want to make a scaled down version of the flag. When two shapes have the same shape but different sizes, we call the shapes similar. There are three ways to solve for a missing side length of a polygon when you are given a pair of similar polygons. There are three ways to solve for a missing side length of a polygon when you are given a pair of similar polygons.
