No. The sides of a shape don't need to be equal in length to be parallel.
A parallelogram is a shape with opposite sides equal in length and parallel to each other. Examples of parallelograms are: rhombus, square, rectangle, and rhomboid.
A kite
rhombus
triunghiul echilateral

A Paralellogram
A trapezoid with even legs is a geometric shape where both of the non-parallel sides (or legs) are of equal length. The parallel sides, on the other hand, are not necessarily equal in length.
a rectangle. it has four parallel sides each side is the same length as the one on the other side.
A trapezoid can also be a parallelogram if its non-parallel sides are of equal length.
The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.
