Trapezoids are not considered parallelograms because parallelograms have 2 pairs of parallel sides, whereas trapezoids have only one. Some definitions of trapezoid say "at least one pair of parallel sides" in which case, some trapezoids would be parallelograms (the ones that have 2 pairs of parallel sides), but most textbooks in the US now define trapezoids as "exactly one pair of parallel sides."

Trapezoids have only one pair of parallel sides. A parallelogram has two pair of parallel sides.

No. A trapezoid only has one pair of parallel sides.

Yes.

No, trapezoids are not rectangles. While both shapes have four sides, rectangles have opposite sides that are equal in length and all interior angles are right angles, whereas trapezoids have only one pair of opposite sides that are parallel.

Trapezoids have only one pair of parallel sides.

By definition, a trapezoid only must have exactly one pair of parallel sides. An isosceles trapezoid does have one pair of congruent sides, but not all trapezoids will have exactly one pair of congruent sides.

Only if it's an isosceles trapezoid otherwise all trapezoids have exactly one pair of parallel sides that are of different lengths

Trapezoids have only one pair of parallel sides. A parallelogram has two pair of parallel sides.

No. A trapezoid only has one pair of parallel sides.

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, because trapezoids have one pair of parallel sides.

Yes, one pair.

Yes.

No, trapezoids are not rectangles. While both shapes have four sides, rectangles have opposite sides that are equal in length and all interior angles are right angles, whereas trapezoids have only one pair of opposite sides that are parallel.
