Rhombus.
An isosceles trapezoid must have a pair of parallel sides and a pair of congruent sides
It is a rectangle or a square.
An isosceles trapezoid has a pair of parallel bases and a pair of congruent sides
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
This quadrilateral is a trapezoid. In a trapezoid, one pair of opposite sides is parallel, and one pair of opposite sides is congruent. The other two sides are not parallel or congruent.

The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.The angles between the sides that are parallel are congruent.
A solid figure that has three pairs of parallel sides and all congruent faces is a cube. A cube has six square faces, and each face is congruent to the others. Additionally, each pair of opposite faces is parallel to one another, satisfying the condition of having three pairs of parallel sides.
No. The congruent sides need not be parallel.
A trapezoid is defined as a quadrilateral with at least one pair of parallel sides. While it typically does not have a requirement for congruent sides, some specific types of trapezoids, such as isosceles trapezoids, do have one pair of congruent non-parallel sides. Therefore, a trapezoid may have one pair of congruent sides, but it is not a defining characteristic of all trapezoids.
That is a trapezoid.
