IM 7.1.3 Practice: Making Scaled Copies

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 1/2.

Draw a scaled copy of Polygon C using a scale factor of 3/2.

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?[br][br]If it is helpful, you may use the coordinate grid below to show your work.

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 of the polygon you drew above? Explain how you know.

Priya and Tyler are discussing the figures shown below. Priya thinks that B, C, and D are scaled copies of A. Tyler says B and D are scaled copies of A. Do you agree with Priya, or do you agree with Tyler? Explain your reasoning.
