Multiple Choice
Select **all** the statements that must be true for _any_ scaled copy Q of Polygon P.
Q has exactly 1 right angle.
If the scale factor is 2, each angle in P is multiplied by 2 to get the corresponding angle in Q.
If the scale factor between P and Q is 51 , then each side length of P is multiplied by 51 to get the corresponding side length of Q.
The side lengths are all whole numbers.
The angle measures are all whole numbers.

Multiple Choice
To make 1 batch of lavender paint, the ratio of cups of pink paint to cups of blue paint is 6 to 5. Find two more ratios of cups of pink paint to cups of blue paint that are equivalent to this ratio.
32
Multiple Choice
Which of the following observations would help you decide that two polygons are not scaled copies?
33
Multiple Choice
Kiran and Mai are standing at one corner of a rectangular field of grass looking at the diagonally opposite corner. Kiran says that if the field were twice as long and twice as wide, then it would be twice the distance to the far corner. Mai says that it would be more than twice as far, since the diagonal is even longer than the side lengths. Do you agree with either of them?
