Quadrilaterals are two-dimensional shapes that have four sides. Quadrilaterals that have only one set of parallel sides are called trapezoids.
trapezoids
A parallelogram always has one set of parallel lines, plus another set also.A trapezoid (trapezium) always has exactly one set of parallel lines and no more.Any shape with more than four sides can have one set of parallel lines, but doesn'tnecessarily have to.
A trapezoid and an isosceles trapezoid
A trapezium. It has one set of parallel sides. It has four sides.
Any regular polygon with an even number of sides will have opposite sides that are parallel. For quadrilaterals (4-sided shapes), a trapezoid has one set of opposite sides and a parallelogram (rectangle, square, rhombus) has both sets of opposite sides parallel.
A trapezoid has one and only one set of opposite sides that are parallel. The other pair of opposite sides are not parallel.
An infinite number of shapes.
A geometric shape with only one set of parallel sides is a trapezoid.
A trapezium (US) has no sides parallel, while a trapezoid has one set of unequal parallel sides.
I think this person means the trapazoid. It has only one pair of parallel sides.
A trapezoid is unique because it is a quadrilateral that has one set of parallel sides, and one set that is not parallel.
