None, normally. One if it is an isosceles trapezium.
None.
It has 1 vertical line of symmetry
All trapeziums have no lines of symmetry unless it is an isosceles trapezium which has one line of symmetry
A trapezium has just the 1 line of symmetry.
Usually none. But one in an isosceles trapezium.
A trapezium can have at most 1 line of symmetry.

A trapezium has just the 1 line of symmetry.
A trapezium has normally no lines of symmetry unless it is an isosceles trapezium which has 1 line of symmetry
A trapezium can have either 0 or 1 line of symmetry, depending on its specific shape. If the trapezium is a parallelogram, it will have one line of symmetry, which is the line that divides the shape into two equal halves. However, if the trapezium is not a parallelogram, it will have no lines of symmetry, as there is no way to divide it into two equal halves through a single line.
Usually none. But one in an isosceles trapezium.
A trapezium (or trapezoid in American English) generally has no lines of symmetry unless it is an isosceles trapezium, which has one line of symmetry that runs vertically through the midpoints of the two parallel sides. In contrast, a regular trapezium with no equal sides or angles has zero lines of symmetry.
None.
