a rectangle and quadrilateral

a rectangle
Presuming our geometry is Euclidean, such a shape would be a rectangle, since all 4 angles would be right angles. If our geometry is hyperbolic, it would be possible to construct such a quadrilateral which is not a rectangle (and in fact, rectangles cannot exist in a hyperbolic geometry). I do not believe such a quadrilateral has any special name.
An oblong in geometry is another word for a rectangle.

A rectangle is defined in plane geometry as a quadrilateral where all four of its interior angles are right angles. Note that this also makes a square qualify as a rectangle, which it is. It's just that the square has all its sides the same length. A rectangel is just longer than a square.
