Types of Polygons
Polygons are two-dimensional geometric figures composed of straight line segments that are connected to each other to form a closed shape. The word “polygon” comes from the Greek language, where “poly” means “many” and “gon” means “angles.” A polygon can have any number of sides, ranging from three to an infinite amount. In this article, we will specifically focus on six-sided polygons, also known as hexagons.
Subtopics:
- Regular hexagon
- Irregular hexagon
- Convex hexagon
Regular Hexagon
A regular hexagon is a six-sided polygon that has six equal sides and six congruent angles. Each interior angle measures 120 degrees, while the exterior angles measure 60 degrees. All vertices of a regular hexagon lie on a circle, making it a cyclic polygon. The symmetry of a regular hexagon is its defining feature, as it can be rotated and reflected while maintaining its original shape and size.
Irregular Hexagon
An irregular hexagon is a six-sided polygon that does not have congruent sides or angles. It has an undefined set of measurements and can be difficult to classify. Examples of irregular hexagons include those with sides of varying lengths or those with angles that do not measure the same degrees.
Convex Hexagon
A convex hexagon is a six-sided polygon where the measures of all interior angles are less than 180 degrees. The vertices of a convex hexagon point outward, and all interior angles face towards the center of the polygon. Convex hexagons can be either regular or irregular, making them a versatile shape in geometry.
| Polygon Name | Number of Sides | Number of Angles | Measure of Each Interior Angle |
|---|---|---|---|
| Regular Hexagon | 6 | 6 | 120 degrees |
| Irregular Hexagon | 6 | 6 | Undefined |
| Convex Hexagon | 6 | 6 | Less than 180 degrees |
Overall, hexagons have a variety of unique properties that make them interesting figures to study in geometry. Whether you are dealing with regular, irregular, or convex hexagons, each type has its own set of characteristics and applications in real-life scenarios.
Characteristics of a Regular Hexagon
A regular hexagon is a six-sided polygon with six equal sides and six equal angles. It is also known as a hexagon because it is a shape with six sides. A regular hexagon can be inscribed in a circle, meaning that the six vertices of the hexagon lie on the circle’s circumference. Due to this property, a regular hexagon has a lot of interesting characteristics that make it a unique polygon.
Properties of a Regular Hexagon
- All six sides of a regular hexagon are equal in length.
- All six angles of a regular hexagon are equal to 120 degrees.
- A regular hexagon can be divided into six equilateral triangles.
- A regular hexagon has rotational symmetry of order 6, meaning that it can be rotated 60 degrees, 120 degrees, 180 degrees, 240 degrees, 300 degrees, and back to its original position.
- The interior angles of a regular hexagon add up to 720 degrees.
Formula for Calculating the Area of a Regular Hexagon
To calculate the area of a regular hexagon, you can use the following formula:
A = (3√3/2) x s^2
Where A is the area of the hexagon and s is the length of one of its sides. The √3 symbol means “square root of 3.”
The Relationship Between a Regular Hexagon and a Circle
A regular hexagon can be inscribed in a circle, meaning that all six vertices of the hexagon lie on the circle’s circumference. Conversely, a circle can also be inscribed in a regular hexagon, meaning that the circle’s center coincides with the center of the hexagon, and the circle touches all six sides of the hexagon at their midpoints. The relationship between a regular hexagon and a circle is essential in mathematics and geometry, and it is useful in various practical applications such as architecture, engineering, and art.
| Shape | Properties |
|---|---|
| Regular Hexagon | 6 equal sides and angles, rotational symmetry of order 6 |

Solving Geometric Problems Using Hexagon
Hexagon is a six-sided polygon with straight sides, and it is one of the most interesting shapes in geometry. It has a unique property that makes it useful in solving geometric problems. In this article, we will explore the concept of hexagon and how it can be used to solve various geometric problems.
The Number 6
The number six is a significant number in mathematics and geometry. It is the sum of the three angles of an equilateral triangle, and it is also the product of two and three, which are the only two consecutive prime numbers. In hexagon, the number six manifests in the six sides and six angles of the shape. The sum of the interior angles of a hexagon is 720 degrees, and each interior angle measures 120 degrees. This makes hexagon an ideal shape for tessellating a plane, as it can fit together seamlessly without leaving any gaps.
Using Hexagon to Solve Geometric Problems
- Area and Perimeter: Find the area and perimeter of a regular hexagon by using the formula A=3/2×(sqrt3 × s²) and P=6s respectively, where s is the length of each side.
- Diagonal length: To find the length of the diagonal of a regular hexagon, use the formula d = 2 x s x (sqrt3), where d is the length of the diagonal and s is the length of one side.
- Angles: The angles of a regular hexagon are all equal, measuring 120 degrees. Knowing this, we can find the measure of any angle in a hexagon by dividing 360 degrees by the number of sides.
Comparison of Hexagon with Other Shapes
Hexagon can be compared with other shapes in terms of area and perimeter. For instance, a hexagon has a larger area than a square or a regular pentagon with the same perimeter. This is an advantage in applications such as designing gardens or building structures where more area is desired. On the other hand, a hexagon has a smaller perimeter than a regular octagon or a round shape with the same area.
| Shape | Perimeter Formula | Area Formula |
|---|---|---|
| Hexagon | P = 6s | A = 3/2×(sqrt3 × s²) |
| Square | P = 4s | A = s² |
| Pentagon | P = 5s | A = 1/4 x (sqrt(5(5+2sqrt5)) x s²) |
| Octagon | P = 8s | A = 2(1+sqrt2) x s² |
In conclusion, hexagon is a remarkable shape with unique properties that make it useful in solving various geometric problems. Its six sides and angles, as well as its area and perimeter formulas, are important concepts to know when studying geometry.
