# Lesson 3

Making Scaled Copies

### Problem 1

Here are 3 polygons.

Draw a scaled copy of Polygon A using a scale factor of 2.

Draw a scaled copy of Polygon B using a scale factor of $$\frac{1}{2}$$.

Draw a scaled copy of Polygon C using a scale factor of $$\frac{3}{2}$$.

### Problem 2

Quadrilateral A has side lengths 6, 9, 9, and 12. Quadrilateral B is a scaled copy of Quadrilateral A, with its shortest side of length 2. What is the perimeter of Quadrilateral B?

### Problem 3

Here is a polygon on a grid.

Draw a scaled copy of this polygon that has a perimeter of 30 units. What is the scale factor? Explain how you know.
