Trapezoid is a quadrilateral.
It has 4 sides.
Two sides are parallel.
2(Adjacent) * * * * * You cannot have a polygon with two sides! A trapezium has four sides - whether it is isosceles or not.
A trapezium has only one pair of parallel sides
A trapezium prism has one plane of symmetry if the trapezium is isosceles, meaning the non-parallel sides are of equal length. This plane of symmetry bisects the prism vertically through the center, dividing it into two mirrored halves. If the trapezium is not isosceles, it has no planes of symmetry.
An isosceles triangle has no parallel sides but it does have two equal sides
7 sides
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.

The 4 interior angles add up to 360 degrees

Isosceles means having equal "legs". It can be a triangle, trapezium or a shape with more sides.
A trapezium has 1 pair of opposite parallel sides of different lengths. Note that sometimes a trapezium is called a trapezoid
It depends on where you are. If in the USA, a trapezium has no parallel sides. For everywhere else, a trapezium has one set of parellel sides (which is called a trapezoid in USA).
It may have none. A trapezium (US) has no parallel sides. A trapezoid (US, known elsewhere as a trapezium) has one side of parallel sides.
