It has 2 classifications which are a trapezoid and an isosceles trapezoid
A trapezoid only has one pair of opposite parallel sides of different lengths but like all other quadrilaterals it has 4 sides.
A trapezoid is different from other quadrilaterals that have 2 pairs of parallel sides in that a trapezoid has only 1 pair of parallel sides of different lengths.
There is no difference from other quadrilaterals because in common with other quadrilaterals it has 4 sides and 4 interior angles that add up to 360 degrees.
There are more than 4 other types of quadrilaterals.A trapezoid has only one pair of parallel sides. All other quadrilaterals have no parallel sides or two pairs.
It has exactly one pair of parallel sides.
A trapezium has one (and only one) pair of parallel sides.
A trapezium has one (and only one) pair of parallel sides.
Not normally because their properties are different but they are both quadrilaterals.
No because a rectangle and a trapezoid have different geometrical properties but they are both 4 sided quadrilaterals.
In the US it's known as a trapezoid in the UK it's known as a trapezium but they are both quadrilaterals.
A 4 sided trapezoid can also be transformed into a 4 sided isosceles trapezoid which will have equal base angles and 1 line of symmetry. Both have a pair of opposite parallel sides of different lengths.
