Congruent triangles ΔDEF and ΔKJI with corresponding sides marked for congruence.
Two triangles, ΔDEF and ΔKJI, are shown with corresponding sides marked as congruent. The sides DE and KJ are marked with single tick marks, EF and JI with double tick marks, and DF and KI with triple tick marks. The vertices are labeled D, E, F, K, J, and I. The task is to complete the congruence statement by naming the corresponding parts.
