Parallogram
A parallelogram has opposite sides and angles congruent which means of equal measure.
It is not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
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.
A general quadrilateral.
It is no different from a quadrilateral.A quadrilateral is any shape with four sides and a rhombus has four sides, therefore it is a quadrilateral.
a pentagon
A square.
A parallelogram.
rhombus
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
A quadrilateral with four equal sides and parallel sides that are not perpendicular to each other is known as a rhombus. In a rhombus, opposite sides are parallel, and all four sides are of equal length. While the angles are not necessarily right angles, the opposite angles are equal, and adjacent angles are supplementary. This shape maintains its properties regardless of the angles between the sides.
If a set of equal sides are adjacent, then the quadrilateral is a "kite" shape. If a set of equal sides are opposite, then the quadrilateral is a parallelogram.
