In class topic: ratios between similar figures. If a and b are the lengths of two corresponding dimensions between two similar figures, then we can say that all corresponding side lengths will be in the ratio


Their area or surface area ratios will be

left(dfrac{a}{b}right)^2 = dfrac{a^2}{b^2}

Their volumes will be in the ratio

left(dfrac{a}{b}right)^3 = dfrac{a^3}{b^3}
