Similar shapes have sides with equal ratios to each other. To find each unknown side, compare its ratio to a known side.

For example, the ratio of the mm side to the mm side should be equal to the ratio of the z side to the
mm side.

You can now use the value of to find ratios for the other unknown sides. Write two more ratios to solve for side and side .
