A rhombus has two opposing acute angles (less than 90º) and two opposing obtuse (greater than 90º) angles, with the opposing sides being parallel and the sides being of equal length. A parallelogram can have the two acute angles and two obtuse angles, but have sides of different lengths. That is: two opposing sides shorter than the other two opposing sides. All angles total 360º
A rhombus has no right angles. A square and a rectangle have right angles. A rhombus is a four sided figure where all sides have the same length and with parallel opposing sides similar to a square. However, while a square has only right angles, a rhombus has two opposing acute angles and two opposing obtuse angles. A rhombus, like a square and rectangle, is a parallelogram, indicating that opposing sides are parallel. A rhombus, square, rectangle and trapezoid are all called quadrilaterals, meaning four sided.
