About This Chapter
Quadrilaterals - Chapter Summary
This chapter reinforces what 3rd through 5th grade students have learned in school about quadrilaterals. Our math instructors created engaging, 5-minute video lessons that define and discuss the properties of various quadrilateral shapes. Each lesson can be watched as many times as necessary to ensure your students understand the materials. The chapter exam gives students an opportunity to show you what they've learned from watching the video lessons.

1. Parallelograms: Definition, Properties, and Proof Theorems
Watch this video lesson to learn how you can identify parallelograms. You will see the unique properties that belong to the parallelogram. You will see the special side and angle characteristics needed to prove a certain shape is a parallelogram.
2. What Is a Rhombus? - Definition and Properties
Watch this video lesson to learn why rhombuses are a special type of quadrilateral. Also, learn why a rhombus is also a parallelogram. Watch as we explore the sides and angles of a rhombus.
3. Kites in Geometry: Definition and Properties
A kite in geometry looks a lot like a kite in the sky! Watch this video lesson to see for yourself. Also, learn about the side and angle properties of kites that make them unique.
4. Rectangles: Definition, Properties & Construction
Watch this video lesson to learn a bit about rectangles. Learn why rectangles are the building blocks of many homes. Also, learn about the properties that make a rectangle unique from other shapes. Finally, learn how you can draw one.
5. Squares: Definition and Properties
Squares can be found in many places in the real world. Watch this video lesson to see how useful they can be and also to learn how to find the perimeter and area of a square.
6. Trapezoids: Definition and Properties
Watch this video lesson to learn what a trapezoid has to do with a triangle. Also, learn the special words that describe the various parts of a trapezoid. You will also see special types of trapezoids.
