-they are both quadrilaterals

Difference

-paralleligram have 2 parallel sides while trapezoid has only 1 parallel side

1) four sides, four vertices

2) The sum of interior angles is 360 degrees.

3) with two diagonals that intersect each other

Differences:

1) Parallelogram has two pairs of opposite parallel sides; trapezoid has only one pair of opposite parallel sides.

2) Parallelogram's diagonals are always congruent, trapezoids diagonals are sometimes congruent.

3) The diagonals of parallelogram bisect each other; trapezoid's diagonals do not bisect each other.

4) The opposite angles of parallelogram are always congruent; Trapezoid's opposite angles are never congruent.
