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.
No, a parallelogram is not a trapezoid.
Square = parallelogram and a square trapezoid = trapezoid Parallelogram = Parallelogram
No, a parallelogram is not always a square, but a square is a parallelogram.
No, a parallelogram is not necessarily square.However, by definition, a square is always a parallelogram.

Some people define trapezoids as having at least one pair of parallel sides. By this definition, all parallelograms are trapezoids, though not all trapezoids are parallelograms.Some people define trapezoids as having exactly one pair of parallel sides. By this definition, the terms "trapezoid" and "parallelogram" are mutually exclusive.
yes a parallelogram is a parallelogram
No, a parallelogram is not a trapezoid.
it is a ............................................................................................. parallelogram
No, a parallelogram is not always a square, but a square is a parallelogram.
The root word in "parallelogram" is "parallelogram".
Square = parallelogram and a square trapezoid = trapezoid Parallelogram = Parallelogram
No, a parallelogram is not always a square, but a square is a parallelogram.
because both lines are paralle so it is a parallelogram
No, a parallelogram is not necessarily square.However, by definition, a square is always a parallelogram.
If it is a parallelogram, then it has two sets of parallelogram sides. Parallelograms' opposite angles are congruent A parallelogram's bisectors are congruent. * * * * * A parallelogram's bisectors are NOT congruent.
