a pentagon has 5 sides total, and no parallel sides. A hexagon has 6 sides, so it has 3 parallel sides. any shape with an odd number of equal sides has 0 parallel sides, no matter how many sides it has. every shape with an even number of equal sides will have the # of sides divided by 2 (#/2) of parallel 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.
