No. (To the extent that I can make any sense out of the question.)
No.
No. Isosceles trapezoids don't have 2 sets of equal sides, which is what a parallelogram is.
trapezoids are never parallelograms.
they are not congruent
No because trapezoids have different properties to that of parallelograms but they are both 4 sided quadrilaterals.
There are absolutely no trapezoids that are also parallelograms.
No but they are both 4 sided quadrilaterals.
Trapezoids
When you join two trapezoids along their parallel sides, you can create a larger shape known as a parallelogram, provided that the trapezoids are oriented correctly. If the trapezoids are of the same size and shape, their union will form a parallelogram with bases equal to the lengths of the trapezoids' parallel sides. Alternatively, if you join them at an angle, you can create a more complex polygon.
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.
Quadrangles that are not parallelograms = trapezoids, kites, any other polygon that is not a parallelogram
