No. A parallelogram by definition has two pairs of parallel sides. A trapezoid by definition has only one pair of parallel sides.
An isosceles trapezoid
Nope A square is a parallelogram By definition a trapezoid is a quadrilateral with only one pair of sides parallel
If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.

An isosceles trapezoid
A trapezoid can be proven isosceles by proving that the 2 legs are congruent (by definition), or that the 2 base angles (either upper or lower) are congruent.

Yes, an isosceles trapezoid is symmetrical.
how is an isoscelels trapezoid related to a isosceles triangle
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
The diagonals of an isosceles trapezoid are equal in lengths
If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
