If Triangle J K L is congruent to Triangle B C A, which statement must be true? Segment J K is congruent to Segment A B Segment J K is congruent to Segment K L Segment J L is congruent to Segment A B Segment J L is congruent to Segment B C

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
