A trapezium. It has one set of parallel sides. It has four sides.
A geometric shape with only one set of parallel sides is a trapezoid.
Square
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
Any shape that is not a triangle may have 2 parallel sides, although regular polygons only have parallel sides when the number of sides is even. For a quadrilateral, a trapezoid(UK trapezium) has 1 set of parallel sides and a parallelogram (either a rhombus, rectangle, or square) has 2 sets of parallel sides.
A geometric shape with only one set of parallel sides is a trapezoid.
trapezium
I think this person means the trapazoid. It has only one pair of parallel sides.
Trapezoid
rectangle
rectange ans square
Only if it is a trapezoid (US usage) with one set of parallel sides, or a parallelogram with both sets of opposite sides parallel. The term quadrilateral only means that the shape has 4 sides.
Hexagon.
A shape that has all parallel sides, like a square, rectangle, or a rhombus. A trapazoid wouldn't be one because only one set of lines are parallel.
A trapezoid has one and only one set of opposite sides that are parallel. The other pair of opposite sides are not parallel.
