Polygon Hierarchy Jonathan McAuley Hierarchy Polygons Definition: A plane figure with at least 3 straight sides and angles, and typically 5 or more. Everything is underneath Polygon because they all can relate to the properties of a polygon. Polygon Real World Example Quadrilaterals Definition: A 4 sided figure which has 4 straight sides. Parallelograms, trapezoids, rectangles, rhombi, and squares are all under quadrilaterals because, they’re all 4 sided figure. Quadrilateral Real World Example Parallelogram Definition: A sided rectangular figure with opposite parallel sides. Parallelograms and trapezoids are next to each other because, they both have opposite parallel sides. Rectangles, rhombi and squares are under because they relate to them having opposite parallel sides. Parallelogram Real world example Trapezoids Definition: It’s a quadrilateral with one pair of parallel sides. Parallelograms and trapezoids are next to each other because, they both have opposite parallel sides. Rectangles, rhombi and squares are under because they relate to them having opposite parallel sides. Trapezoids Real World Example Rectangles Definition: It’s a 4 side figure with opposite parallel sides and 2 sides are the same and the other 2 are the same. Rectangles are next to rhombi because they both have 4 sides but in both figure 2 sides are the same and the other 2 are the same. Squares are under it for a reason. Rectangles Real World Example Rhombus Definition: It’s a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides. Rectangles are next to rhombi because they both have 4 sides but in both figure 2 sides are the same and the other 2 are the same. Squares are under it for a reason. Rhombus Real World Example Squares Definition: It’s a 4 sides figure with opposite parallel sides and all sides are equal. Squares are at the bottom because they are a 4 sides shape and relate to it all having opposite parallel sides but all sides are equal. Squares Real World Example
