An arrowhead can be described as a 4 sided quadrilateral.
A quadrilateral having the given angles would best be described as an irregular 4 sided quadrilateral but depending where you live there may be another name for it.
A quadrilateral as described is a parallelogram. If the angles between the two sets of parallel lines are 90 degrees, the shape is a rectangle, a special form of parallelogram.
Since all of the cube's faces are the same they all are or none of them are. A square can be a rectangle but a rectangle can't be a square. A rectangle is described as a quadrilateral with four 90 degree angles or two sets of parallel lines. A square is described as a quadrilateral with equal sides and two sets of parallel lines. All faces of a cube is are rectangles.
If it is a quadrilateral it cannot be "not a quadrilateral"!
