C. Both pairs of opposite sides are congruent and parallel.
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
This figure is infact a square, because a square it the only regular quadrilateral.
A quadrilateral is a shape with four sides. A parallelogram is a quadrilateral that has two pairs of parallel sides (i.e. the sides opposite each other are parallel). A rectangle, for example, is a parallelogram. A trapezoid, however, is an example of a quadrilateral that is not a parallelogram - it has four sides, but only two of them are parallel to each other.

No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.

A quadrilateral with only two parallel sides is only a quadrilateral ...... because we don't know whether the parallel sides ar equal or not .............. so it is only a quadrilateral ............
A quadrilateral that has only one pair of parallel sides (the other pair not parallel) is a trapezium.
C. Both pairs of opposite sides are congruent and parallel.
No, a parallellogram is a quadrilateral with two pair of congruent sides and a trapezoid is a quadrilateral with only one pair of congruent sides.
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
Yes, a trapezoid is a quadrilateral with only one pair of parallel sides.
"It is a quadrilateral with exactly one pair of parallel sides." is the true one. Some people define it as having at least one pair of parallel sides, so if your teacher is one of those people then all of the answers are wrong, but since all of the other answers are definitely wrong then this is the only one that could be right.
Square
A square or a rhombus
The only quadrilateral that fulfills both criteria is a rectangle ( a square is a special rectangle where all 4 sides are congruent).
