Properties of parallelogram:

Parallelogram is a quadrilateral with two pairs of parallel sides.
The opposite sides of a parallelogram are of equal length.
The opposite angles of a parallelogram are of equal measure.
The diagonals of a parallelogram bisect each other.
The area of a parallelogram = (base)*(height).
Opposite sides of a parallelogram never intersect.

Vertices of a triangle or a rectangular cube are the points at which the sides (lines of triangle or rectangular cube) meet.

so if DS question, statement 1 says: ab=cd, bc=da

then is that sufficient to know that its a parallogram?
