1. What Are Polygons? - Definition and Examples
Watch this video lesson to see how the shapes that you grew up with are all related. Learn why the shapes of bricks, stars, and street blocks are considered polygons while the sun, moon, and rolling hills are not.
2. Equilateral & Equiangular Polygons: Definition & Examples
In this lesson, we will discuss definitions and examples of special polygons--geometric figures with straight sides. Equilateral ones have matching side lengths. Equiangular ones have matching angles. Some polygons have both.
3. Triangles: Definition and Properties
What makes a shape a triangle? In this lesson, we'll explore the definition of a triangle, then analyze the parts of triangles, including the vertices, base and height.
4. What is a Quadrilateral? - Definition, Properties, Types & Examples
This lesson explains the definition and properties of a quadrilateral. We will look at examples of two categories of quadrilaterals. At the end, you will be able to test your knowledge with a quiz.
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.
7. 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.
8. 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.
9. 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.
10. What is a Pentagon? - Shape, Area & Definition
This lesson will prepare you to work with pentagons by teaching you the definition, description of the geometric shape, and the formula for finding its area.
11. What is a Hexagon? - Definition, Area & Angles
Hexagons are interesting geometric shapes and appear in many areas of nature and life. In this lesson, learn all about the hexagon, its angles, and how to find its area. When you have finished, review what you've learned with our short self-assessment quiz!
12. Congruent Polygons: Definition & Examples
In this lesson, you'll review what polygons are, and you'll discover the conditions that polygons must meet in order to be congruent. Then, you can test your knowledge with a brief quiz.
13. How to Translate, Rotate & Reflect Polygons
In this lesson, we will study transformations of figures and show how this concept could be used to decode a message. Using examples, we will learn about translations, rotations and reflections of polygons.
14. Polygons: Symmetry & Vertices
In this lesson, we'll go over the basics of what polygons are, specifically focusing on symmetry in polygons and where the vertices can be found. We'll look at examples and images to examine these concepts.
15. How to Find the Number of Diagonals in a Polygon
At first, you might think that the diagonals of a polygon are pretty useless, but watch this video lesson to learn how diagonals are used in real life. You will learn the formula to find how many diagonals a polygon has as well as how to use it.
