The diagonals of the KMNP rhombus meet at point O. Find the angles of the KOM triangle if the KNP angle is 80 degrees.

| By the property of the diagonals of the rhombus, the diagonals are the bisectors of the angles at the vertices of the rhombus, then the angle KNM = KNP = 80. In the rhombus, the opposite angles are equal, then the angle PNM = PKM, which means the angle MKO = 80.
The diagonals of the rhombus intersect at point O at a right angle, which means the angle KOM = 90.
Then the angle KMO = 180 – 90 – 80 = 10.
Answer: The angles of the triangle KOM are equal to 90, 80, 10.
