Similar polygons are a type of geometric figure where two or more polygons have the same shape but may differ in size. They are related by a scale factor and are related by a proportion. Learning the properties of similar polygons is a valuable skill in mathematics. In this lesson 4 skills practice, we will look at the properties of similar polygons and how they are used.

## Similar Polygons Definition

Similar polygons are shapes with equal angles but different side lengths. They are related by a scale factor which is the ratio of the side lengths. For example, if two polygons have sides of length 3 and 6, respectively, the scale factor is 2. This means that the side of the larger polygon is twice as long as the side of the smaller polygon.

## Properties of Similar Polygons

The properties of similar polygons include: (1) Their corresponding angles are congruent; (2) Their corresponding sides are proportional; (3) The scale factor between the polygons is constant; (4) The scale factor is the ratio of the side lengths; and (5) The scale factor is the same for all pairs of corresponding sides. These properties can be used to find the area, perimeter, and other properties of similar polygons.

## How to Use Properties of Similar Polygons

The properties of similar polygons can be used to find the area, perimeter, and other properties of similar polygons. For example, if you have two polygons with sides of length 3 and 6, respectively, then the scale factor is 2. This means that the area of the larger polygon is twice the area of the smaller polygon. Similarly, the perimeter of the larger polygon is twice the perimeter of the smaller polygon. These properties can be used to solve for other properties of similar polygons, such as the volume and surface area.

## Conclusion

In this lesson 4 skills practice, we explored the properties of similar polygons and how they are used. Similar polygons have equal angles and sides that are proportional to one another. They are related by a scale factor which is the ratio of the side lengths. The properties of similar polygons can be used to find the area, perimeter, and other properties of similar polygons.
