What is a parallelogaram?
Unfortunately, there is no such thing as a parallelogaram. However, I'm sure you were refering to the shape known as a parallelogram. A parallelogram is a quadrilateral with two sets of parallel sides. Parallel, by the way, means two lines going in the exact same direction that will never cross. Keep in mind that, for example, a square can be a parallelogram while still being a square and a rectangle can be a parallelogram while still being a a rectangle.

Why is a trapezoid also a parallelogram?
First of all, a trapezoid is not always a parallelogram. Did you mean the reverse: "Why is a parallelogram also a trapezoid"? If so, this depends upon your definition of a trapezoid and parallelogram. Some people define a trapezoid as a quadrilateral with exactly one pair of parallel sides, and a parallelogram as a quadrilateral with exactly two pairs of parallel sides. According to these definitions, a trapezoid can *NEVER* be a parallelogram, so your question is meaningless. However, others might define a trapezoid as a quadrilateral with one *or two* pairs of parallel sides. If you use this definition, then all parallelograms are also trapezoids, much in the same manner that all squares are also rectangles.
