How would you describe scale factor? Select all that apply:

• Two shapes that change in size but not shape.

• A number that multiplies all the sides of a shape to make a scaled copy.

• A number that multiplies the size of a shape to make a scaled copy.

Why is the scale factor 2? Select all that apply:

• Because all the sides got multiplied by 2.

• Because

  6 * 2 = 12

  10 * 2 = 20

  & 8 * 2 = 16

• Because they look the same.

• Because it says it is.
