It is given that JKLM is a rectangle. By the Response area, ∠JML and ∠KLM are right angles, and because all right angles are congruent, ∠JML≅∠KLM. JM¯¯¯¯¯¯≅KL¯¯¯¯¯ because Response area, and ML¯¯¯¯¯¯≅ML¯¯¯¯¯¯ by the Response area. By the Response area, △JML≅△KLM. Because corresponding parts of congruent triangles are congruent, JL¯¯¯¯¯≅MK¯¯¯¯¯¯¯.
