How do you classify quadrilaterals?
Based on the parallel (II) sides.
Kites have no II sides.Trapezoids have 1 pair of II sides.Parallelograms have 2 pairs of II sides
The sum of all interior angles is 360.

There are 3 types of quadrilaterals.
Quadrilaterals are differentiated
based on their number of
parallel sides.
