A scale factor of 7 means to add 7 to every side of one polygon to create a new polygon. It depends on the number of sides It depends on the angle sum Never Always

Actually, a scale factor of 7 means you multiply the lengths of every side of the original polygon by 7 to create a new, larger polygon. So it’s not about adding 7; it’s about stretching! This transformation preserves the shape but increases the size. To apply a scale factor correctly, make sure to understand that every corresponding side length scales up (or down, if the factor is less than 1). A common mistake is thinking scaling changes angles, but it doesn’t—the angles remain the same; it's just the sides that get longer or shorter!
