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?

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

Type your answer below:
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.
