A rhombus is a quadrilateral (4 sided polygon) with 4 sides equal in length. The rhombus is a special case of parallelogram, so the opposite angles are equal, and adjacent angles are supplementary (add up to 180°).
A square is a rhombus which also has all 4 angles equal to 90°.

A parallelogram can have four equal sides that will not meet at right angles. The term diamond can also be used in this context.

A rhombus is a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
A figure with four equal sides and no right angles is a rhombus. A rhombus is comprised of two acute angles and two obtuse angles.
A four sided figure with four equal sides and no right angles is a diamond, or a rhombus. If it had four right angles, it would be a square.
