Best Answer

A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid.

It is isosceles of the non-parallel sides are of equal length.

It is right angled if any one of the angles is 90 degrees.

Q: Describe the characteristics that make a quadrilateral a trapezoid and what an isosceles trapezoid and a right trapezoid must have?

A trapezoid is a quadrilateral with one pair of parallel sides.

A quadrilateral is a generic term used to describe a four sided polygon. In other words, it is a shape that has four sides.A rectangle, rhombus, parallelogram and trapezium (trapezoid) has four sides. In light of this, it can be classified as a quadrilateral but, if the quadrilateral has no sides and angles equal, it could not be classified as any of the foregoing.

The description given fits that of an isosceles trapezoid whereas non parallel sides are equal in length and base angles are equal in sizes.

I assume you mean 1 pair of parallel lines, which would describe a trapezoid.

An isosceles trapezoid is a 4 sided quadrilateral having one pair of opposite parallel sides of different lengths and its two slanted sides are of the same lengths and it has one line of symmetry.

A trapezoid is a quadrilateral shape that has four sides of unequal lengths two of which are parallel to each other. An isosceles trapezoid also has two parallel sides but with two other sides being of equal length.

A trapezoid is a quadrilateral with one pair of parallel sides.

Yes because a trapezoid is a 4 sided closed shape which is a quadrilateral.

Not all trapezium are Isosceles.

Not really. In "American" English a trapezium is a quadrilateral with no sides parallel. In "British" English a trapezium is a quadrilateral with two sides parallel. --- however --- You need to compare these usages with trapezoid.... which sees the definitions almost reversed. In "American" English a trapezoid is a quadrilateral with only one pair of parallel lines. In "British" English a trapezoid is a quadrilateral with no sides parallel. -- Note -- A British "trapezium" could arguably include a square.

A trapezoid/trapezium is a quadrilateral (4 sided shape) with exactly one pair of parallel sides.It is a quadrilateral (a closed plane shape with four linear sides) that has at least one pair of parallel lines for sides

A trapezium is a quadrilateral (a four sided figure) where no two sides are parallel.This is the American English usage. The British English usage would be to call this an irregular quadrilateral. Previously, it was called a trapezoid, but that has a different meaning today.
