$\overline{DF}$=8 $\overline{EF}$=11 $\overline{DE}$=10

Work Step by Step

It is clearly mentioned in the question that the triangles are congruent. which indicates that $\overline{AC}$=$\overline{DF}$ $\overline{AB}$=$\overline{EF}$ $\overline{BC}$=$\overline{DE}$ and measures of $\overline{AC}$=8 $\overline{AB}$=11 $\overline{BC}$=10 therefore $\overline{DF}$=8 $\overline{EF}$=11 $\overline{DE}$=10
