What Are Polygons? - Definition and Examples

1. What Are Polygons? - Definition and Examples

Polygons are flat shapes with at least three sides. Learn the definition of a polygon, discover the differences between a regular and irregular polygon, and then explore examples of concave, convex, simple, and complex polygons.

Equilateral & Equiangular Polygons: Definition & Examples

2. Equilateral & Equiangular Polygons: Definition & Examples

Equilateral polygons have sides of the same length while equiangular polygons have interior angles that are the same. Learn more about the definitions of equilateral and equiangular polygons and how to identify common examples.

Triangles: Definition and Properties

3. Triangles: Definition and Properties

Triangles are shapes with three sides and three angles that lie on a two dimensional plane. Study the definition and properties of triangles including sides and angles, base and height, and opposite and adjacent sides.

What is a Quadrilateral? - Definition, Properties, Types & Examples

4. What is a Quadrilateral? - Definition, Properties, Types & Examples

A quadrilateral is a closed figure with four straight sides. Learn the properties which make a shape a quadrilateral, how to locate its sides and vertices, and the difference between a concave and convex quadrilateral.

Squares: Definition and Properties

5. Squares: Definition and Properties

A square is a shape with four equal sides and four 90-degree angles. Explore the definition and properties of a square, how to calculate its perimeter and area, and examples of squares in the real world.

Trapezoids: Definition and Properties

6. Trapezoids: Definition and Properties

A trapezoid is a four-sided shape with exactly one pair of parallel sides. Learn about the definition and properties of trapezoids, explore relevant terms related to trapezoids, and discover different kinds of special trapezoids.

Parallelograms: Definition, Properties, and Proof Theorems

7. Parallelograms: Definition, Properties, and Proof Theorems

A parallelogram is a flat shape with four sides, with opposite sides that are equal and parallel. Study the definition of a parallelogram, the properties of the shape including sides and angles, and how to use proof theorems to identify this shape.

What Is a Rhombus? - Definition and Properties

8. What Is a Rhombus? - Definition and Properties

Rhombus is a special type of parallelogram with four equal sides and two parallel opposite sides. Learn about the definition of a rhombus, understand why it is considered a quadrilateral and a parallelogram, and discover the properties of its angles.

Rectangles: Definition, Properties & Construction

9. Rectangles: Definition, Properties & Construction

Rectangles are unique from other shapes. In this lesson, discover how to define a rectangle, explore the properties of rectangles, and learn how to draw one.

What is a Pentagon? - Shape, Area & Definition

10. What is a Pentagon? - Shape, Area & Definition

A pentagon, named after the Greek word for 'five,' has exactly five sides and angles. Learn the different types of pentagon shapes and how to calculate the area of a pentagon using the formula provided in two example problems.

What is a Hexagon? - Definition, Area & Angles

11. What is a Hexagon? - Definition, Area & Angles

A hexagon is a shape with six sides, six angles, and six vertices. Understand the definition of a hexagon, explore regular and irregular hexagons, and learn how to find the area of a hexagon.

Congruent Polygons: Definition & Examples

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.

How to Translate, Rotate & Reflect Polygons

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.

Polygons: Symmetry & Vertices

14. Polygons: Symmetry & Vertices

Polygons are two-dimensional shapes with at least three straight lines and no curves. Learn the components of polygons by exploring the vertices where sides meet and the concept of lines of symmetry in polygons.

How to Find the Number of Diagonals in a Polygon

15. How to Find the Number of Diagonals in a Polygon

A polygon has straight sides, is flat in shape, and contains diagonals. Explore the definition of a diagonal and a polygon, and learn how to use a simple formula to find the number of diagonals in a polygon.
