# Given AB of length 7.3 cm and CD of length 3.4 cm, construct a line segment XY

Given $\overline { AB }$ of length 7.3 cm and $\overline { CD }$ of length 3.4 cm, construct a line segment $\overline { XY }$ such that the length of $\overline { XY }$ is equal to the difference between the lengths of $\overline { AB }$ and $\overline { CD }$. Verify by measurement
