A rhombus is a special case of a parallelogram, where all sides are equal length. A rhombus and a parallelogram have the opposite vertices are equal angles, but adjacent angles are not necessarily equal.

A parallelogram with equal length sides is a RHOMBUS. A parallelogram with equal sides and the four angles are at 90 degrees is a SQUARE.

A rhombus would be one. Parallelogram have four sides with opposites equal in length.

A rhombus. A square is a special case of a rhombus.

A RHOMBUS has four equal sides. However, it opposite angles are equal ,but its adjacent angles are NOT equal , but sum to 180 degrees.

rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.

Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.

No. Squares have to have four sides of equal length and four angles of equal size. It is possible however, to have a trapezium which is not a parallelogram. Also a rhombus is a parallelogram with four sides of equal length and two pairs of equally sized angles.
