Which statement is not used to prove that ΔLKM is similar to ΔNOM? triangles LKM and NOM in which point O is between points K and M and point N is between points L and M Angle K is congruent to itself, due to the reflexive property. Angles MON and MKL are congruent, due to the corresponding angles postulate. KM is a transversal intersecting LK and ON. Segments KL and ON are parallel.
