An octagon is neither a quadrilateral nor a parallelogram.

"Quadrilateral" refers to a shape that has four sides.

"Parallelogram" refers to a shape that has two pairs of opposite, congruent sides.

An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
