A parallelogram.
A description that states a quadrilateral has one pair of opposite sides that are both equal and parallel does not guarantee that it is a parallelogram. While this condition is sufficient for proving that a quadrilateral is a parallelogram, it is not necessary; other configurations might exist where a quadrilateral meets this condition without being a parallelogram. Other descriptions, such as having both pairs of opposite sides equal or both pairs of opposite angles equal, would guarantee it is a parallelogram.
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
To determine if a quadrilateral is a parallelogram, you can check if either pair of opposite sides is parallel and equal in length, or if the diagonals bisect each other. Additionally, if both pairs of opposite angles are equal, or if one pair of opposite sides is both parallel and equal in length, then the quadrilateral is a parallelogram. If any of these conditions are met, you can confidently classify the quadrilateral as a parallelogram.
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
true
A parallelogram.
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.
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
If a quadrilateral has two pairs of opposite congruent sides, then the quadrilateral is a parallelogram.
A quadrilateral is a parallelogram if it has two pairs of (opposite) sides that are parallel.
A parallelogram is such a shape.
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.
A quadrilateral with both pairs of opposite sides congruent is a parallelogram.
