Any Parallelogram is divided into two congruent Triangles by each of its diagonal. In a parallelogram, the sum of squares of diagonals is equal to sum of squares of sides. Here a question arises that does a parallelogram have Rotational Symmetry? The answer to this question is yes, a parallelogram possesses rotational symmetry. It provides a same view after its rotation also. Adjacent angles of any parallelogram are supplementary that is their sum is 180 0. There are four types of parallelogram, as follows: Square: A Square is defined as a parallelogram whose all four sides is equal and opposite sides are parallel.
