For one thing it can be a trapezoid because there are two equals side.
I've heard that called a "kite" before.

Yes, because a square is a parallelogram
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
An octagon is neither a quadrilateral nor a parallelogram. "Quadrilateral" refers to a shape that has four sides. "Parallelogram" refers to a shape that has two pairs of opposite, congruent sides. An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
A quadrilateral with both pairs of opposite sides congruent is a parallelogram.
That's not possible. No rhombus (quadrilateral with two pairs of equal sides) cannot be a parallelogram.
A 'KITE' ; two adjacent sides may be of equal length. A parallelogram has two pairs of equal and parallel sides.
A parallelogram
A quadrilateral with only two pairs of parallel sides
A parallelogram is such a shape.
A parallelogram.

Yes, because a square is a parallelogram
Yes, if both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is indeed a parallelogram. This is one of the properties that define parallelograms: if a quadrilateral has two pairs of sides that are equal in length, it ensures that the opposite sides are parallel. Thus, the statement is true based on the properties of quadrilaterals.
To determine if a quadrilateral is a parallelogram, you need to show that either pairs of opposite sides are equal in length, or that pairs of opposite angles are equal, or that the diagonals bisect each other. Alternatively, if both pairs of opposite sides are parallel, it also confirms that the quadrilateral is a parallelogram. Any one of these conditions is sufficient to classify the quadrilateral as a parallelogram.
