A trapezium has only 1 pair of parallel lines.
A trapezium can have at most 1 line of symmetry.
None, normally. One if it is an isosceles trapezium.
A trapezium has no right angles therefore there are no perpendicular lines. If it had perpendicular lines, it would be a square or rectangle.
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.

A trapezium has one set of parallel lines and the one of them has the lines of symmetry but the other one doesn't have any. Trapezium doesn't have perpendicular lines
