(a) The four sides are unequal.

(b) Sum of the interior angles = 4 right angles or 360 degrees.

(c) The two diagonals intersect.

(d) The line joining the mid-points of any two adjacent sides is parallel to the corresponding diagonal and equal to half of it.

(e) Lines joining the mid points of the sides of a quadrilateral in an order form a parallelogram.

(f) The sum of the four exterior angles is 4 right angles.

(g) The sum of the four interior angles is 4 right angles.
