Question
in triagle ABC and triagle DEF, AL perpendicular BC, DM perpendicular EF, AB=DE, AC=DF, AL=DM. show that triagle ABC congruent triagle DEF
A={1,2,3,4} and B={2,4,6}.If (A unionB)={1,2,3,4,6} and (A intersection B)={2,4} and (A intersection B) is subset of set C and set c is subset of (A union B) then find C
