# Who first invented circle?

Who first invented circle? This is a question that has puzzled historians and mathematicians for centuries. The answer, it turns out, is rather complicated. It is believed that the first person to truly understand the concept of a circle was Greek mathematician Euclid, who lived around 300 BCE.

However, the first person to actually draw a perfect circle is unknown. What we do know is that the concept of a circle has been around for thousands of years and has been used in everything from art to architecture to mathematics. In this blog post, we will explore the history of the circle and how it has been used throughout the ages.

So, who first invented circle? Euclid is the first person who is believed to have understood the concept of a circle. However, the first person to actually draw a perfect circle is unknown. The history of the circle is fascinating, and the concept has been used in a variety of disciplines over the years.

## The history of the circle

The first recorded instance of a circle was from the 3rd millennium BC in Europe. The earliest known example of a perfect circle was drawn by the Greek mathematician Pythagoras in the 6th century BC. In China, the first circles appeared in the Zhou dynasty (11th–3rd centuries BC).
The circle is a very old geometric shape that has been used in various cultures for centuries. It is one of the most basic shapes in geometry and has many mathematical properties.

A circle is created when a point moves in a constant direction and distance from another point. The distance between the two points is called the radius of the circle. The point that remains stationary is called the center of the circle.

A circle can be either open or closed. An open circle is simply a curved line, while a closed circle is a geometric shape with no endpoints.

A circle is said to be inscribed in a polygon if all the vertices of the polygon are on the circumference of the circle. A circle is said to be circumscribed about a polygon if all the sides of the polygon are tangent to the circumference of the circle.

The area of a circle is equal to πr2, where r is the radius of the circle. The perimeter (circumference) of a circle is equal to 2πr, where r is again the radius of the circle.

## The first person to invent the circle

The Ancient Egyptians were the first to invent the circle, which they did by drawing a perfect circle in the sand. The Ancient Greeks were the first to use the term “circle,” which they did to describe the shape of the sun and moon. The first person to actually calculate the circumference of a circle was Archimedes, who did so by measuring the circumference of a large cylinder.

## How the circle has been used throughout history

The circle has been used throughout history as a symbol of unity, perfection, and infinity. It is often seen as a holy symbol, and has been used in religious and spiritual ceremonies for centuries. The circle is also a popular design element in many works of art. It is said that the first person to invent the circle was Pythagoras of Samos, a Greek mathematician and philosopher who lived in the 6th century BCE.

## The different types of circles

There are many different types of circles, each with its own unique properties. The most common type of circle is the Euclidean circle, which is defined as a set of points in a plane that are equidistant from a given point, called the center. Other types of circles include the Apollonian gasket, the Sierpinski carpet, and the Mandelbrot set. Each of these has its own interesting properties that make it unique.

## Conclusion

We may never know who first invented the circle, but we can appreciate its perfection nonetheless. The circle is a simple shape that can be found everywhere in nature, from the Sun to water droplets. Its simplicity is what makes it so beautiful and timeless. Whether you’re looking for a symbol of perfection or just want to appreciate the beauty of nature, take a look at the circles around you and give thanks to whoever invented them.
