# Ch 38: 6th-8th Grade Geometry: Quadrilaterals

The brief and entertaining video lessons in this chapter on quadrilaterals show 6th-8th graders how to identify the properties of different mathematical shapes. Students can re-watch videos and review lesson transcripts to improve retention.

## 6th-8th Grade Geometry: Quadrilaterals - Chapter Summary

Watch the video lessons in this chapter to guide your students through an examination of quadrilaterals. Easy and entertaining videos discuss the properties of trapezoids, parallelograms, and more, in addition to showing students the relationships between many of these shapes. While watching the videos, you can click on video tags to move between main points. Also, you can test your students' understanding of quadrilaterals through having them take lesson quizzes.

## Chapter Lessons and Objectives

Lesson Objectives
What is a Quadrilateral? - Definition, Properties, Types & Example Instructors discuss the characteristics that define this type of shape.
Parallelograms: Definition, Properties, and Proof Theorems Students will learn how to describe and draw a parallelogram, examine the properties of this shape, and review the theorems used to prove if a parallelogram is a quadrilateral.
What Is a Rhombus? - Definition and Properties This lesson explains and sketches a rhombus, establishes its properties, and verifies the connection between quadrilaterals and rhombuses.
Kites in Geometry: Definition and Properties Instructors show and illustrate the properties of a kite, and then compare a kite to a rhombus.
