a. Given b. Reflexive property of congruence c. $\triangle JKM$ d. $\triangle LMK$
a. This is one of the given statements. b. This is the reflexive property of congruence. It just means that a figure is congruent to itself because the same line forms a line on each of the triangles. For c. and d., we have the final statement of the proof, stating that what we wanted to prove has been proven. c. $\triangle JKM$ d. $\triangle LMK$
