The Spatial Midpoint Quadrilateral Theorem
The Spatial Midpoint Quadrilateral Theorem
The midpoints of the sides of any quadrilateral in space form a planar parallelogram. The controls allow you to create a wide range of three-dimensional quadrilaterals, yet the blue polygon always remains a parallelogram.
