Yes, every rectangle is a parallelogram. Parallelograms are defined as a shape with opposite, but parallel sides. A rectangle is defined as a shape with 90 degree angles, 2 sets of parallel sides, and the opposite sides must be equal in length. Because the sides of any rectangle are parallel, any qualified rectangle is a parallelogram.

YES!!! It is a special case of parallelogram, in that every angle is 90 degrees.
I hope you know the definition of the parallelogram. i.e.,In geometry, a parallelogram is a quadrilateralwith two sets of parallel sides.so naturally rhombus and rectangle are special case of parallelogram. That means every rhombus is parallelogram similarly every rectangle is a parallelogram. But converse need not be true.So parallelogram not necessarily a rhombus or a rectangle.GMG.
Every rectangle is also a parallelogram and a quadrilateral.
Every rectangle is a parallelogram. The description of a parallelogram is: -- a figure that lies in a single plane -- it has four sides -- opposite sides are parallel -- opposite sides have equal lengths -- alternate angles are equal Every rectangle satisfies this description.
A rectangle is a parallelogram but a parallelogram is not a rectangle. A rectangle needs all 90 degree angles but a parallelogram dosnt.
A rectangle is a parallelogram but a parallelogram need not be a rectangle and so they are not the same.
