Answer for screen readers
An isosceles trapezoid is not a parallelogram because it has only one pair of parallel sides, whereas a parallelogram has two pairs of parallel sides.
More Information
An isosceles trapezoid has one pair of parallel sides and its non-parallel sides (the legs) are of equal length. This differs from a parallelogram, which always has two pairs of parallel sides.
Tips
A common mistake is to assume that any quadrilateral with two equal sides is a parallelogram. Always check for the requirement of having two pairs of parallel sides.
