SUMMARY
The discussion focuses on calculating the angles of a rhombus given that the angle between the diagonal and a side is 22º30’. The calculations confirm that angle B is 45º, angle D is also 45º, while angles C and E are both 135º. The total interior angles of the rhombus sum up to 360º, consistent with the properties of rhombuses. The method used effectively utilizes the congruency of opposing angles in a rhombus.
