A Kite.
You might call it a quadrilateral, but you would not call it a square or rhombus.
It has four sides of equal length and four angles of equal size.
A Square a square Quadrilateral I think
There is no specific name for such a quadrilateral.
A parallelogram.
A rhombus is a quadrilateral with four equal sides.
The sum of the four sides of a quadrilateral is equal to its perimeter.
Well, you are supposed to call an irregular quadrilateral an IRREGULAR QUADRILATERAL. Haha. There really isn't any name for a regular quadrilateral. You just call it a quadrilateral or whatever the shape is. You could call it a REGULAR QUADRILATERAL.
A quadrilateral with 4 equal sides is called a square
You would be talking about an equilateral quadrilateral which is the rhombus (four sided polygon with sides of equal length). This also includes the square.
