What are the multiple properties of diagonals of a trapezium?

A rhombus is a parallelogram whose diagonals are perpendicular to each other. Important formulas for a Rhombus. If a and b are the lengths of the diagonals of a rhombus, Area = (a* b) / 2; Perimeter = 4L; Trapezium. Properties of a Trapezium. The bases of the trapezium are parallel to each other (MN ⫽ OP). No sides, angles and diagonals are congruent. read more

Trapezium. Its properties are (a) Opposite sides are parallel. (b) Two pairs of adjacent angles add up to 180 degrees. (c) The two non-parallel sides can be equal or unequal. (d) When the two non-parallel sides are equal and two pairs of adjacent angles are equal it is called an isosceles trapezium. (e) The diagonals intersect. read more
