A right-lined quadrilateral figure, whose opposite sides are parallel, and consequently equal; -- sometimes restricted in popular usage to a rectangle, or quadrilateral figure which is longer than it is broad, and with right angles.
A quadrilateral with opposite sides that are parallel
A quadrilateral with 2 pairs of parallel sides, 2 pairs of equal angles, and 2 pairs of equal sides.
A shape with four sides in which the sides opposite each other (both pairs) are parallel.
A quadrilateral with opposite sides parallel and equal in length.
a quadrilateral whose opposite sides are both parallel and equal in length
a four-sided figure (a quadrilateral ) whose opposite sides are parallel
a four sided figure in which opposite sides are parallel and also, congruent
a four sided geometric form, in which opposite sides are of equal
a four sided polygon that includes implicit constraints to keep the opposite sides parallel
a four-sided polygon where each of the four sides is the same length
a four-sided polygon whose opposite sides are parallel
a geometric figure with opposite sides the same length
a quadrilateral (four-sided figure) that has opposite sides that are parallel
a quadrilateral in which the opposite sides are parallel
a quadrilateral that has two pairs of opposite sides that are parallel and equal to one another
a quadrilateral with both pairs of opposite sites parallel
a rectangle if its diagonals are equal and are at right angles and its converse
a rectangle if its diagonals have equal length and its converse
a rhombus if its diagonals are perpendicular and its converse
a special kind of quadrilateral
a square if it is both a rhombus and a rectangle
a trapezoid with the other pair of opposite-sides parallel, also
A quadrilateral whose opposite sides are parallel and congruent.
(n) A quadrilateral (four-sided polygon) in which opposite sides are parallel. The square, rectangle, rhombus, and rhomboid are all parallelograms.
a four-sided plane figure with opposite sides parallel
A quadrilateral with opposite sides parallel and congruent.
A quadrilateral that has two pairs of parallel sides. Pairs of opposite sides and opposite angles of a parallelogram are congruent.
quadrilateral whose opposing sides are parallel
A four-sided polygon, quadrilateral, with opposite sides equal and parallel.
A four-sided rectilineal figure whose opposite sides are parallel; sometimes spec. applied to a rectangle.
a quadrilateral with both pairs of opposite sides parallel
A quadrilateral that contains two pairs of parallel sides.
A quadrilateral that has two pairs of parallel and equal opposite sides.
A quadrilateral with two pairs of parallel and congruent sides.
A quadrilateral with opposite sides parallel and therefore opposite angles equal.
A quadrilateral in which both pairs of opposite sides are parallel (Lesson 2.7).
a four-sided figure in which the opposte sides are parallel to each other and the opposite sides have the same length.
A parallelogram is a four-sided plane figure that has two sets of opposite parallel sides. Every parallelogram is a polygon, and more specifically a quadrilateral. Special cases of a parallelogram are the rhombus, in which all four sides are of equal length, the rectangle, in which the two sets of opposing, parallel sides are perpendicular to each other, and the square, in which all four sides are of equal length and the two sets of opposing, parallel sides are perpendicular to each other.
