A defining attribute is that it has two pairs of parallel sides. There are lots of other attributes which can be derived from this.
No.
No, not every parallelogram has all the attributes of a square. While all squares are parallelograms (having opposite sides equal and angles that are equal), not all parallelograms have equal side lengths and right angles, which are characteristic of squares. Therefore, a parallelogram may lack the specific properties that define a square.
A rhombus is a special kind of parallelogram (all its sides are of the same length). So things that are true of a parallelogram are true of a rhombus. It has two sets of parallel sides, its adjacent angles are supplementary. Other attributes, that follow from these also apply.
1. All 4 sides same length 2. Is a parallelogram 3. Opposite angles are equal 4. Can be a square if all angles are 90°
Yes all rectangles are parallelogram but all parallelogram cannot be rectangles.

A parallelogram where all sides are equal is a square.
Yes.A parallelogram with all congruent sides is called a rhombus. A square is technically a parallelogram with all congruent sides as well.
A rhombus is a parallelogram, but a parallelogram isn't always a rhombus. A rhombus is a parallelogram where all the lines are the same length.
A rectangle is a parallelogram but a parallelogram is not a rectangle. A rectangle needs all 90 degree angles but a parallelogram dosnt.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
First, there is no such word as trapozoid: it is trapezoid although most of the world know it as a trapezium.Whereas a trapezium has one pair of parallel sides, a parallelogram has two pairs of parallel sides.
A parallelogram is a 4 sided quadrilateral.
Because a rectangle is a parallelogram.
