##### Description:

You will be able to answer the following questions:

1. Identify the properties of special quadrilaterals
2. Compare the properties of different quadrilaterals
3. Classify quadrilaterals by specific properties

A quadrilateral is any polygon with 4 sides. There are 7 special types of quadrilaterals: Trapezoid, Isosceles Trapezoid, Parallelogram, Rectangle, Rhombus, Square, and Kite. Each quadrilateral has its own set of unique properties. Just as people have properties that describe them (such as tall, short, brown hair, or blue eyes), each quadrilateral has properties that uniquely identify it. By the end of this lesson, you should know when sides are congruent or parallel, when angles are congruent or bisected, and when diagonals are congruent, perpendicular, or bisected.
