Quadrilateral $$A B C D$$ is reflected across line $$m$$ to create quadrilateral $$A^{\prime} B^{\prime} C^{\prime} D^{\prime}$$. ![](http://admin.getprephub.com/media/editor/tp2_20230125193127178324.png) What is the length of segment $$\overline{B C}$$ ?

Answer Since $$A^{\prime} {B}^{\prime} {C}^{\prime} {D}^{\prime}$$ is the reflection of $$A B C D$$ across line $$m$$. Therefore, by comparing $$A B C D$$ and $$A^{\prime} B^{\prime} C^{\prime} D^{\prime}$$, $$B C=B^{\prime} C^{\prime}=41$$ units,
