Open Pantograph



   What is the geometrical shape associated with an open pantograph?

Answer:          Parallelogram: A Parallelogram is a rectangle whose angles are no longer right angles, while its opposite sides remain parallel and equal, and its diagonals still bisect the parallelogram into two equal triangle areas. However, its total area will always be less than the area of the rectangle from which it was formed.
