**drwls**, Wednesday, January 12, 2011 at 12:26pmThe triangles are similar (but not congruent).

That means that corresponding sides are all in the same ratio.

BC/EF = 12/10 = AC/DF = 18/DF

DF = 18*(5/6) = 15

**helper**, Wednesday, January 12, 2011 at 12:27pmby ratios

DF/10 = 18/12

solve for DF
