Important Circle Parts. Radius: The distance from the center of the circle to its outer rim. Chord: A line segment whose endpoints are on a t Circles‎: ‎Two or more circles that inter. circle. A circle is easy to make: Draw a curve that is "radius" away from a central point. And so: All points are the same distance from the center. A circle (black), which is measured by its circumference (C), diameter (D) in cyan, and radius (R) in red; its centre (O) is in magenta. A circle is a simple closed shape. It is the set of all points in a plane that are at a given distance That circle is sometimes said to be drawn about two points. The proof is in two parts. First, one.

It does not cut the circumference. The point at which it touches is called the point of contact.

A tangent is a straight line which touches the circle. It does not cut the circumference. Given a line and a circle, it could either be touching the circle or non-touching as shown below: In the first fig.

Definitions of Parts of Circles

The line AB here is called secant of the circle. The line segment PQ is known as the chord of circle and its parts circle as its endpoints lie on the circumference of the circle.

A chord passing through a center of the circle is known as the diameter of the circle and it is the largest chord of the circle. In the second figure, the line AB touches the circle exactly at one point, P.

The circle is a highly symmetric shape: Its symmetry group is the orthogonal group O 2,R. The group of rotations alone is the circle group T. All circles are similar. A circle's circumference and radius are proportional.

The area enclosed and the square of its radius are proportional. The circle that is centred at the origin with radius 1 is called the unit circle.

Thought of as a great circle of the unit sphereit becomes the Riemannian circle. Through any three points, not all on the same line, there lies a unique circle. In Cartesian coordinatesit is possible to give explicit formulae for the coordinates of the centre of the circle and circle and its parts radius in terms of the coordinates of the three given points.

Chord Chords are equidistant from the centre of a circle if and only if they are equal in length. The perpendicular bisector of a chord passes through the centre of a circle; equivalent statements stemming from the uniqueness of the perpendicular bisector are: A line that "just touches" circle and its parts circle as it passes by is called a Tangent.

And a part of the circumference is called an Arc.
