If it also has two lines of reflectional symmetry then it must be a rhombus or a rectangle.Everyone has seen shapes with four sides, but parallelograms are a bit special. They stand out because their opposite sides are always parallel to each other. But that's not all that makes them interesting. In this guide, we're going to take a closer look at parallelograms, diving into their unique features and properties.Properties of a Parallelogram. Property 1: Sides opposite to each other are equal in length i.e. PQ = SR and QR = PS. Property 2: Angles opposite to each other are equal i.e. ∠P =∠R and ∠Q = ∠S. Property 3: The Diagonals bisect one another (at the point of their intersection) i.e. PO = RO and QO= SO.
