7 Sides Of Polygon: Understanding The Basics
As we delve into the world of geometry, one of the fundamental shapes that we encounter is the polygon. With its straight sides and angles, polygons form the building blocks of some of the most complex shapes we come across in our daily lives. In this article, we will delve into the seven-sided polygon, also known as the heptagon, and explore its properties and applications.
What is a Heptagon?
A heptagon, as the name suggests, is a polygon with seven straight sides and angles. It is a two-dimensional shape that belongs to the family of polygons, which means it lies flat on a plane surface. The heptagon is a regular polygon, which means that all its sides and angles are equal in measure.
Properties of a Heptagon
Let us take a closer look at the properties of a heptagon:
- It has seven straight sides and angles.
- All its sides and angles are equal in measure.
- The sum of all its internal angles is equal to 900 degrees.
- Its external angles add up to 360 degrees.
- It has seven diagonals.
- It is a cyclic polygon, which means that all its vertices lie on a common circle.
- It is a regular polygon, which means that it can be inscribed in a circle.
How to Calculate the Area of a Heptagon
The area of a heptagon can be calculated using the following formula:
Area = ((7 × s2) / 4) × (1 / tan(180 / 7))
Where s is the length of one of its sides.
Applications of Heptagons
Heptagons can be found in a variety of real-world applications. Some examples include:
- The shape of some stop signs and traffic signs.
- The geometry of some crystals and minerals.
- The shape of some musical instruments, such as the Indian tabla.
- The shape of some coins, such as the British 50p coin.
- The shape of some sports grounds, such as the Rugby League playing field.
Types of Heptagons
There are two types of heptagons: regular and irregular. A regular heptagon is a heptagon where all its sides and angles are equal in measure. An irregular heptagon is a heptagon where its sides and angles are not equal in measure.
Regular Heptagon
A regular heptagon can be constructed using a compass and a straightedge. Its construction involves drawing a circle and dividing its circumference into seven equal parts using a compass. The points where the circle intersects with these seven parts are the vertices of the heptagon. Connecting these vertices with a straightedge creates the heptagon.
Irregular Heptagon
An irregular heptagon can be constructed using a variety of methods. Its construction involves drawing seven straight sides and angles that are not equal in measure. One way to construct an irregular heptagon is by using a protractor and a ruler. This involves measuring and drawing the angles and sides systematically.
Conclusion
The heptagon is a fascinating shape that has many applications in the real world. Understanding its properties and how to construct it can help us appreciate its role in the world of geometry. Whether you are a student, a professional, or just a curious learner, the heptagon is a shape worth exploring.
So, take out your compass and straightedge, and start exploring the world of heptagons!
