A trapezium is a quadrilateral with exactly one pair of opposite sides parallel to each other
- In trapezium, exactly one pair of opposite sides are parallel
- The diagonals intersect each other
- The non-parallel sides in the trapezium are unequal except in isosceles trapezium
- The line that joins the mid-points of the non-parallel sides is always parallel to the bases or parallel sides which is equal to half of the sum of parallel sides
