When all the vertices of a plane quadrilateral are exactly equal to 90 degrees it is is called a rectangle and, if all its sides are of equal length, that rectangle is called a square. So when a plane quadrilateral has all its vertices exactly equal to 90 degrees, but it does not have all its sides equal in length, it must be a rectangle but not a square.

A quadrilateral that is not a rectangle is a kite. A quadrilateral is a figure that has four straight sides. A rectangle has opposites sides that are parallel and of equal measurement. However, a kite is a quadrilateral by definition but is unlike a rectangle because it has pairs of equal adjacent sides.
Shapes that do not have equal sides is called a quadrilateral. They include an irregular quadrilateral, rectangle, or a parallelogram.

Not necissarily. Quadrilateral simply says it has 4 sides. A rectangle has perpendicular sides. Equilateral means that the sides are of equal length (like a square, which is a special case rectangle)

Yes. A quadrilateral is any plane figure bounded by four straight lines. A rectangle is a quadrilateral with each of its vertex angles equal to 90°, opposite sides are parallel and of equal length but the pairs of opposite sides are of different lengths. A square is a rectangle with all its sides equal in length.
