The document defines different types of triangles and angles. It then discusses quadrilaterals, identifying them as 4-sided polygons. It defines 5 specific quadrilaterals: parallelograms, rectangles, rhombi, squares, and trapezoids. For each shape, it provides the key attributes like number of parallel sides, angle measures, or side lengths that can be used to identify and describe each quadrilateral. It concludes by instructing the reader to copy a chart with names, drawings and descriptions of quadrilaterals from Buckle Down page 86.
