A circle is a geometric shape that is defined as the set of all points in a plane that are a fixed distance from a given point, called the center of the circle. The distance from the center of the circle to any point on the circle is called the radius of the circle.

One of the most notable characteristics of a circle is that it is a symmetrical shape. This means that if you were to draw a line through the center of the circle, the circle would be divided into two equal halves that are mirror images of each other. This symmetry is also reflected in the properties of the circle, such as the fact that all points on the circumference of the circle are equidistant from the center.

Another important characteristic of a circle is that it has no corners or vertices. This means that a circle is a smooth, continuous curve. This property is important in many practical applications, such as the design of gear wheels and wheels for vehicles, where the smoothness of the circle allows for efficient and reliable operation.

In terms of its geometric properties, a circle has a unique relationship with its radius. For example, the circumference of a circle is equal to 2π times the radius, where π is a mathematical constant that is approximately equal to 3.14. The area of a circle is equal to π times the radius squared. These relationships between the radius and the circumference and area of a circle are known as the circle's circumference formula and area formula, respectively.

In addition to its geometric properties, a circle has many practical applications. For example, circles are often used in the design of circular objects such as wheels, coins, and gears. Circles are also used in many areas of science and technology, such as in the design of circular tanks and containers, and in the measurement of angles in geometry.

Overall, the characteristics of a circle make it a useful and important shape in many different fields. Its symmetry, smoothness, and unique geometric properties make it a versatile and valuable tool for designers, engineers, and mathematicians alike.

## Psychology of Shapes See the figure below explaining the arc, sector and segment of a circle. Alternative Method Let us derive in another way. Were the central angle ACB to be drawn, a sector would be defined that would include all of the segment created by the chord AB. . With the addition of a variety of colours it promotes community and diversity.

The area of a circle depends on the length of its radius. They can be weather presenters or sole researchers. A good example of the community aspect is the Wikipedia logo. Ans: The properties of a circle related to a chord are: i A perpendicular from the centre of the circle to the chord bisects the chord.

## Circles in Maths Interior and Exterior of a Circle Consider the circle with center P and radius r. The points within the hula hoop are not part of the circle and are called interior points. A circle is a closed curve that is drawn from the fixed point called the center, in which all the points on the curve are having the same distance from the center point of the center. A sector of a circle is the region enclosed by the central angle of a circle and the circle itself. The circle is only composed of the points on the border. Solved Examples Example 1: Consider a circle whose center is at the origin and radius is equal to 8 units.

## Characteristics of Circles What are the scientists who study the weather called? Center of a Circle The center of a circle is the center point in a circle from which all the distances to the points on the circle are equal. For example points U and V lie on the circle. The Equator and all diagrammatically opposite longitudes touch the center of a circle and therefore are Great Circles. The Sector of a Circle: The sector of a circle is a part of the circle that is enclosed by two radii and an arc of the circle as a part of its boundary. Quality management tools ensure changes in the systems and processes which eventually result in superior quality products and services. All such circles must pass through or touch the center of the circle.

When two radii meet at the center of the circle to form the sector, it actually forms two sectors. Like when you cut a cake you begin your pieces in the middle. The fixed point is known as the origin or centre of the circle, and the fixed distance between the points is known as the radius.
