Calculate the angles of a rhombus if the angle between the side and the diagonal is 20 degrees

The diagonals of a rhombus are the bisectors of its corners. Therefore, the two angles of the rhombus are 40 °. By the property of the parallelogram angles: 180 ° – 40 ° = 140 ° – the degree measure of the second pair of angles.
Answer: 40 °. 40 °, 140 ° and 140 °.
