Draw

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

Draw

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

Multiple Choice

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?

• 12
• 16
• 14
• 10

Draw

Draw a scaled copy of this polygon so that the scaled copy has a perimeter of 30 units.

Open Ended

What is the scale factor? Explain how you know.

Multiple Select

Select **all** quadrilaterals that are scaled copies of the unlabeled rectangle. Explain how you know.

• G

• B

• C

• A

• E

Draw

On graph paper, draw a different scaled version of the original rectangle.

Multiple Choice

If Quadrilateral Q is a scaled copy of Quadrilateral P created with a scale factor of 3, what is the perimeter of Q?

• 150
• 200
• 175
• 186

Open Ended

Quadrilateral A has side lengths 3, 6, 6, and 9. Quadrilateral B is a scaled copy of A with a shortest side length equal to 2. Jada says, “Since the side lengths go down by 1 in this scaling, the perimeter goes down by 4 in total.” Do you agree with Jada? Explain your reasoning.
