YES!!! The 'quad' prefix means '4'. However, quadrilaterals can have different names , depending on their characteristics. Square Reactangle Rhombus Parallelogram Trapezium Kite
what do yo mean by formulas? Are you asking for the different characteristics of quadrilaterals that make some squares and some rhombuses? There is not really a formula for a quadrilateral.
a rectangle has 4 right angles, a parallelogram has 2 acute angles and 2 obtuse angles
A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid. It is isosceles of the non-parallel sides are of equal length. It is right angled if any one of the angles is 90 degrees.

The key characteristics of a parallelogram is that it is a quadrilateral with two pairs of parallel sides. Everything else follows for that.
trapezoid
A quadrilateral is a 4 sided shape whose 4 interior angles add up to 360 degrees.
Triangles have only three sides; all quadrilaterals, including parallelograms, have four.
Common characteristics of triangles and quadrilaterals:Both are polygons.Neither end with "-gon."Both have vertices.A quadrilateral can be split into 2 triangles and they both have exterior angles that add up to 360 degrees

If it is a quadrilateral it cannot be "not a quadrilateral"!

quadrilateral
A series of transformations on quadrilateral S resulted in quadrilateral T. The angles of quadrilateral S and T are congruent but the sides of quadrilateral T are twice as long as quadrilateral S. Which transformation on quadrilateral S must be included to result in quadrilateral T * sorry thats the full question!
