Actually, there are several names for a rectangle that are correct. A rectangle is a polygon, a quadrilateral, and even, sometimes, a square.
A rectangle.
parallelogram
It does not have a specific name.
Square
The most precise name for a shape that is both a rectangle and a rhombus is a square. A square is a quadrilateral with four equal sides and four right angles, meeting the criteria of both a rectangle (opposite sides are equal and parallel, and angles are right angles) and a rhombus (all sides are equal). Therefore, a square is the most specific term to describe a shape that is both a rectangle and a rhombus.
Any quadrilateral in which at least one (and therefore at least two) angles are not right angles is not a rectangle. The majority of these do not have a specific name.
Yes, for both.
It has no specific name. It is unusual, though, because its length is smaller than its width!
An oblong is a rectangle BUT a rectangle isn't necessarily an oblong. There are 2 types of rectangle: 1) Square (equal sided) 2) Oblong (unequal sided) Most refer to an oblong as a rectangle and use the word 'square' to be more specific as it has different properties.
