Is a trapezoid also a parallelogram? Explain why or why not.

No, it is not since it has only one pair of parallel sides. In a parallelogram, both pairs of opposite sides are parallel and equal.
Trapeziod needs just 2 sides to be parrelel. Parallelogram requires all sides to be parallel. 
my teacher dose not teach us that
