The diagonal of the rhombus forms an angle of 80 degrees from one of its sides. Find the corners of the diamond.

Since the diagonal of the rhombus divides the angle at its vertex in half, one of the corners of the rhombus will be equal to 2 * 80 = 160. The sum of the adjacent angles of the rhombus is 180, then the second angle of the rhombus is 180 – 160 = 20.
Answer: The angles of the rhombus are 20 and 160.
