This document provides definitions and properties of different types of quadrilaterals, including rectangles, rhombi, squares, parallelograms, rhombuses, isosceles trapezoids, and trapezoids. Each quadrilateral shape is defined by key properties such as equal or parallel sides, right angles, bisecting or perpendicular diagonals, and angle sums. The document serves as an introduction to basic quadrilateral shapes and their distinguishing mathematical characteristics.
