This could be a rectangle or rhomboid (tilted rectangle) , or more specifically a square or rhombus, where the side lengths are all the same.
All are special cases of the parallelogram, which has at least one pair of parallel sides, but not necessarily congruent ones.
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 congruent pairs of adjacent sides and no parallel sides is a kite.
* both pairs of opposite sides are parallel * both pairs of opposite sides are congruent * both pairs of opposite angles are congruent * one pair of opposite sides are parallel and congruent * both diagonals bisect each other * all consecutive angle pairs are supplementary
A parallelogram is a quadrilateral with opposite sides parallel and congruent.
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)

parallelogram.
That's a rhombus.
That's a parallelogram.
Parallelogram
A quadrilateral with both pairs of opposite sides congruent is a parallelogram.
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
A quadrilateral with congruent pairs of adjacent sides and no parallel sides is a kite.
There are 5 ways to prove a Quadrilateral is a Parallelogram. -Prove both pairs of opposite sides congruent -Prove both pairs of opposite sides parallel -Prove one pair of opposite sides both congruent and parallel -Prove both pairs of opposite angles are congruent -Prove that the diagonals bisect each other
* both pairs of opposite sides are parallel * both pairs of opposite sides are congruent * both pairs of opposite angles are congruent * one pair of opposite sides are parallel and congruent * both diagonals bisect each other * all consecutive angle pairs are supplementary
No, all that is required is that it has four straight sides.
