How many parallel sides has a trapezium?
It has a 1 pair of opposite parallel sides of different lengths
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
Yes a trapezium has at least 1 pair of parallel lines however there is dispute that it may have 2 pairs of parallel lines.
A trapezium is a quadrilateral with two parallel lines.
