A scale factor is a ratio between two corresponding sides of similar shapes. A scale factor describes how much a shape has been scaled up or down. To scale a shape up or down, you multiply every side length of a shape by the scale factor to increase or decrease the size. The sizes of the angles do not change.
What is a scale factor? A scale factor describes how much a shape has been enlarged. We multiply every side length of a shape by the scale factor to enlarge it. The sizes of the angles do not change. Enlarging a shape by a scale factor greater than 1 will make the shape bigger. E.g. Shape A has been enlarged by scale factor 2 to give shape B .
