How is the scale factor between two shapes determined?

• By dividing the length of a side in one shape by the length of the corresponding side in another shape

• By dividing the length of a side in one shape by the length of the non-corresponding side in another shape

• By adding the lengths of corresponding sides

• By multiplying the lengths of corresponding sides
