# parts of a circle model – tlm

In this blog post we write about making of the parts of a circle model – tlm – maths working model – diy – simple and easy using cardboard and color paper

A circle is a geometric shape that is defined as a set of points in a plane that are all the same distance from a central point. The following are the main parts of a circle:

1. Center: The center of the circle is the point that all the points on the circle are equidistant from. It is the midpoint of the circle.
2. Radius: The radius of a circle is a line segment that connects the center of the circle to any point on the circle. It is half of the diameter of the circle.
3. Diameter: The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. It is the longest distance across the circle.
4. Circumference: The circumference of a circle is the distance around the circle. It can be calculated using the formula C = 2πr, where C is the circumference, π is the mathematical constant approximately equal to 3.14, and r is the radius of the circle.
5. Arc: An arc of a circle is a portion of the circumference of the circle. It is defined by two points on the circle and the portion of the circumference between those points.
6. Sector: A sector of a circle is a region bounded by two radii and an arc of the circle. It is a portion of the circle that is enclosed by the two radii and the arc.
7. Chord: A chord of a circle is a line segment that has its endpoints on the circle. It is the straight line that connects the two endpoints of an arc.
