| Since the height of the rhombus divides the side in half, it is also the median of the triangle, and therefore the triangle ABD is equilateral and AB = BD = AD. In an equilateral triangle, all angles are 60, then the angle BAD = ABD = BDA = 60.

Since the diagonals of the rhombus divide the angle at the apex in half, the angle ABC = 2 * ABD = 2 * 60 = 120.

In a rhombus, the opposite angles are equal, therefore, the angle BAD = BCD = 60, the angle ADC = ABC = 120.

AB = P / 4 = 20/4 = 5 cm.

ВD = 5 cm.

Answer: The angles of the rhombus are 600 and 1200.
