rhombus
A parallelogram (or rectangle) which is not a rhombus (or square).
A regular quadrilateral is a square. It is a four-sided figure with all sides being the same length and all angles equal (right angles).
Any rectangle will have diagonals that are equal. Don't forget that since squares are also a special type of rectangle that they would also have congruent diagonals as well.
First of all, quadrilaterals are just shapes with 4 sides! The word "quadrilateral" comes from the Spanish word "cuatro" which means four. One shape that has all sides equal length and is a quadrilateral is a square. Another one is a rhombus. Because it has 4 equal sides that are the same length. That easy! I hope this helps!
A Rectangle.
You are a square or a rectangle
You are a square
Two features of a rhombus are it is a quadrilateral shape because it has 4 sides which are equal in length and it has no corner right angles but its diagonals are perpendicular.
a square
A Rhombus * * * * * WRONG! A rhombus does not have equal diagonals. If it did it would be a square! The shape is a special case of a kite.
Any quadrilateral (4-sided shape) has 2 diagonals.
a pentagon
square
It is no different from a quadrilateral.A quadrilateral is any shape with four sides and a rhombus has four sides, therefore it is a quadrilateral.
A "parallelogram" technically is a shape where opposite sides are equal and any shape with four sides is a "quadrilateral". Every square has four sides of equal length, so a square is both a parallelogram and a quadrilateral. A rhombus(or diamond shape) can have four sides of equal length and can be a parallelogram as well, so either are possibilities.
Two pairs of touching sides are the same length. The diagonals meet at right angles. Opposite sides are not parallel.
