A trapezoid is a type of quadrilateral that could not be a parallelogram, as it has at least one pair of parallel sides, but does not require the other pair to be parallel. In contrast, a parallelogram must have both pairs of opposite sides parallel. Therefore, while all parallelograms can be considered quadrilaterals, not all quadrilaterals, such as trapezoids, can be classified as parallelograms.
360. Any quadrilateral's angles add up to 360.
No. The only conditions to quality as a parallelogram is that it is a quadrilateral, and that opposite sides are parallel.
