# Quadrilateral Diagram

**The best way to classify a quadrilateral is by using the most specific classification.**

**Quadrilateral diagram**.
1 with a partner create a venn diagram or a tree diagram which relates all quadrilaterals.
In fact it is a 4 sided polygon just like a triangle is a 3 sided polygon a pentagon is a 5 sided polygon and so on.
In a convex quadrilateral all interior angles are less than 180 and the two diagonals both lie inside the quadrilateral.

Quadrilateral just like there are for triangles. A vowel diagram or vowel chart is a schematic arrangement of the vowels depending on the particular language being discussed it can take the form of a triangle or a quadrilateral. They still have 4 sides but two sides cross over.

As you move down the hierarchy the classification becomes more specific. When two sides cross over we call it a complex or self intersecting quadrilateral like these. Convex quadrilaterals by symmetry represented with a hasse diagram.

The flow or family chart clearly states the relationship between the quadrilaterals along with their properties to help 5th grade and 6th grade learning. Kites trapezoids rectangles rhombi squares parallelograms answers may vary in how the venn diagram is designed to fit rhombi and squares within kites. Irregular quadrilateral british english or trapezium north american english.

Vertical position on the diagram denotes the vowel closeness with close vowels at the top of the diagram and horizontal position denotes the vowel backness with front vowels at the left of the diagram. A quadrilateral is a polygon. The diagram below shows the quadrilateral hierarchy.
