This document defines and describes various polygons, including triangles, quadrilaterals, pentagons, hexagons, and octagons. It specifically focuses on different types of quadrilaterals such as parallelograms, rectangles, squares, rhombuses, and trapezoids. Key characteristics are provided, such as opposite sides being parallel and equal length for parallelograms, four right angles for rectangles, and all sides being equal length for squares. Special relationships between the quadrilaterals are also noted, such as rectangles, rhombuses, and squares all being types of parallelograms.
2. Vocabulary
