Part A)

Draw a scaled copy of either Figure A or B using a scale factor of 3.

Draw your scaled copy on paper, take a picture, and upload it using the image upload icon

If you do not have the ability to upload an image of your work type "Scaled copy is on paper."

Part B)

Draw a scaled copy of either Figure C or D using a scale factor of 1/2.

Draw your scaled copy on paper, take a picture, and upload it using the image upload icon

If you do not have the ability to upload an image of your work type "Scaled copy is on paper."

Part A)

Diego and Jada want to scale this polygon so the side that corresponds to 15 units in the original is 5 units in the scaled copy.

Diego and Jada each use a different operation to find the new side lengths. Here are their finished drawings.

What operation do you think Diego used to calculate the lengths for his drawing?

Part B)

What operation do you think Jada used to calculate the lengths for her drawing?

Part C)

Did each method produce a scaled copy of the polygon? Explain your reasoning.

Part A)

Andre wants to make a scaled copy of Jada's drawing so the side that corresponds to 4 units in Jada’s polygon is 8 units in his scaled copy.

Andre says “I wonder if I should add 4 units to the lengths of all of the segments?” What would you say in response to Andre? Explain or show your reasoning.

Part B)

Create the scaled copy that Andre wants. If you get stuck, consider using the edge of an index card or paper to measure the lengths needed to draw the copy.
