A rhombus is a quadrangle or quadrilateral with four equal sides and no right angles. A rhombus is a type of parallelogram, which is any quadrangle with equal opposite sides and angles. A rhombus appears to be a distorted or tilted square.
The angles in a rhombus vary based on whether it is close to a square or flatter in structure. A rhombus resembling a square could have one pair of matching angles at 95 degrees and the other pair at 85 degrees. A more stretched rhombus could have one angle pair at 105 degrees and the other at 75 degrees.
