Question

Is the polygon similar? If so, by what rule?​

Answer 1

`\bf \stackrel{\textit{\Large sides}}{\stackrel{left}{\cfrac{10}{30}}=\stackrel{top}{\cfrac{12}{36}}=\stackrel{right}{\cfrac{10}{30}}=\stackrel{bottom}{\cfrac{2}{6}}}\implies \stackrel{\textit{same ratio}}{\cfrac{1}{3}}\qquad \textit{\Large similar figures~~\checkmark}`
