"Quadrilateral" just means any closed shape with four sides. It doesn't say
anything about the relationship, comparison, or position of any of the sides.
A quadrilateral has four sides that may or may not be equal or parallel If two sides are parallel and the other sides equal but not parallel it is a trapezoid
It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.
A kite has two pairs of equal sides with no parallel sides.
The parallel sides of a trapezoid are of different lengths.
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
An isosceles triangle. It has two pairs of equal sides, which are also not parallel.
No. It is a lie.
A circle or a sphere
In the U.S., that is a specific kind of "trapezium", which is a quadrilateral with no parallel sides.AnswerA quadrilateral with no parallel sides and no equal sides is basically just that, a quadrilateral.
a rhombusNotice that if all 4 sides are equal, then they must be parallel.
A trapezium can have 0, 2 or 3 sides of equal length.0 equal sidesThis is the general state of a trapezium.2 equal sidesThe two parallel sides can never be equal.The two non-parallel sides can be equal. In this case, the trapezium is an isosceles trapezium.Or one of the parallel sides can be equal to one of the non-parallel sides. No special name.3 equal sidesThese would have to be the two non-parallel sides and one of the others. The trapezium is isosceles.
Any regular polygons with an even number of sides can have opposite sides equal and parallel.For quadrilaterals, if any two sides are equal and parallel, the other two sides must also be equal and parallel, and it is a parallelogram (square or rhombus). If the equal sides are not parallel, the figure is a trapezoid (UK trapezium).
