This document discusses different types of quadrilaterals including trapezoids, kites, parallelograms, rectangles, rhombuses, and squares. It provides definitions and properties for each shape. Key properties include: 1) A trapezoid has one pair of parallel sides, leg angles are supplementary, and the midsegment is half the sum of the bases. 2) A kite has two pairs of consecutive congruent sides, perpendicular diagonals, and one pair of opposite angles are congruent. 3) Parallelograms have opposite sides parallel and opposite angles congruent. Rectangles and squares are types of parallelograms with right angles or all sides congruent.
