no, all trapezoids are members of the quadrialteral family
All trapezoids must be quadrilateral. And, as the name suggests a quadrilateral has four sides.
The quadrilateral is a 4-sided polygon, quadrilaterals consist of kites, trapezoids, squares, rectangles, rhombuses, and parallelograms. The regular quadrilateral polygon is the square.
Yes - some trapezoids can have one line of symmetry.
Yes. Those trapezoids with four right angles are called squares. Since in order to be a trapezoids, a shape must be a quadrilateral with with one set of parallel lines, and a square fits those requirements. In conclusion, the trapezoids that have four right angles are squares.

trapezoids and rectangles, are both quadrilateral (which means shapes with 4 sides). rectangles and trapezoids are also polygons.
Yes a trapezoid is a quadrilateral. Quadrilateral means "four sided", and trapezoids have four sides.
All trapezoids must be quadrilateral. And, as the name suggests a quadrilateral has four sides.
Yes.
Some trapezoids, not all.
Some are, and some are not. A trapezoid is a special kind of quadrilateral ... one in which two of the four sides are parallel. So all trapezoids are quadrilaterals, but there are also a lot of other quadrilaterals that are not trapezoids.
No. There are many counterexamples including trapezoids and kites.
No but a trapezoid is always a 4 sided quadrilateral
Yes. To be a trapezoid, a quadrilateral must have one pair of sides that are parallel. Since rhombuses are parallelograms, they are all also trapezoids, so a subset of trapezoids are rhombuses.
There is no one type. Examples of quadrilaterals that are not parallelograms are trapezoids and kites.
Yes, because a trapezoid has 4 sides. A trapezoid is a special kind of quadrilateral, one in which two of the four sides are parallel. So all trapezoids are quadrilaterals, but there are also a lot of other quadrilaterals that are not trapezoids.
