# Create a nest of 5 sets whose largest set in the set of all polygons. For each set but the largest set in the nest, write a deffinition that precisly describs the objects in that set in terms of the objects in the next larger level. my solution to this qesttion is: all polygons Quadrilalateral tarpezoid Isosceles Traingle Rectangle But i'm not sure about that. Also, i need their deffinitions?

all polygons
> quadrilaterals (all polygons with 4 sides)
> convex quadrilaterals (all quadrilaterals in which all internal angles are <180)
> trapezoid(all convex quadrilaterals with at least one pair of opposite sides parallel)
> quadrilateral parallelogram (all convex quadrilaterals with both pairs of opposite sides parallel)
> rectangle (all quadrilateral parallelograms with internal angles 90 degrees)
> square (all rectangles with adjacent sides equal)
