No. Most Trapezoids are not isosceles. The non parallel sides must be congruent to be isosceles.
There are isosceles trapezoids which are sometimes called regular trapezoids.
Isosceles trapezoids, squares, and rectangles.
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.
No trapezoids are parallelograms, and no parallelograms are trapezoids.
NO rectangles are trapezoids

Yes
There are isosceles trapezoids which are sometimes called regular trapezoids.
Yes
No. Isosceles trapezoids don't have 2 sets of equal sides, which is what a parallelogram is.
No, not all trapezoids are scalene. A trapezoid is defined as a quadrilateral with at least one pair of parallel sides, and it can have varying side lengths and angles. Some trapezoids can have two sides of equal length, making them isosceles trapezoids, while others can have all sides of different lengths, classifying them as scalene. Thus, trapezoids can be either scalene or isosceles.
Only when they are isosceles trapezoids.
Only when it is an isosceles trapezoid otherwise no.
Yes.
Only if it's an isosceles trapezoid otherwise all trapezoids have exactly one pair of parallel sides that are of different lengths
Isosceles trapezoids have 2 (occasionally 3) equal sides and have 2 pairs of equal angles, but that's not case if they're not isosceles.
