In triangle MNP, point K lies on the side MN, and the angle is NKP-acute. Prove that KP.

Given triangle mnr k intersects mn angle ncr acute prove cr proof: angle NKP – acute → angle MKP – obtuse triangle MKP MKP – obtuse angle angle KMP – acute angle MPK – acute opposite a larger angle lies a large side (consequence) => KR < MR.
