Trapezium (Uk English)
an octagon it has eight sides
trapezoid
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 geometric shape with only one set of parallel sides is a trapezoid.
A shape that has 2 right angles, only 1 set of parallel sides, and no lines of symmetry is a right trapezoid (or right-angled trapezium). In this trapezoid, the two non-parallel sides are not equal in length, contributing to the lack of symmetry. The right angles are formed between one of the parallel sides and one of the non-parallel sides.
A trapezoid perhaps?
A right trapezium.
A trapezium. It has one set of parallel sides. It has four sides.
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.
The description given fits that of a trapezoid
trapezium
A quadrilateral with exactly one set of parallel lines is known as a trapezoid (or trapezium in some countries). In this shape, one pair of opposite sides is parallel, while the other pair is not. The parallel sides are referred to as the bases, and the non-parallel sides are called the legs. Trapezoids can have various forms, including isosceles trapezoids, where the legs are of equal length.
