If we have a parallelogram where all sides are congruent then we have what is called a rhombus. The properties of parallelograms can be applied on rhombi. If we have a quadrilateral where one pair and only one pair of sides are parallel then we have what is called a trapezoid.
TopParallelogram is defined as a type of quadrilateral having four sides, its opposite sides are equal and parallel to each other. Corresponding opposite angles is also equal to each other. 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. Rectangle: A Rectangle is defined as a parallelogram whose opposite sides are equal and parallel. Rhombus: A Rhombus is defined as a type of parallelogram whose four sides are equal in length.
