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.
