- Circle and its Parts. The different parts of a circle are listed below: Circumference. Radius. Diameter. Chord. Tangent. Secant. Arc. Segment. Sector. Let us discuss each of the parts in detail.
- Circumference of a Circle. The circumference of a circle is its boundary. In other words, when we measure the boundary or the distance around the circle, that measure is called the circumference and it is expressed in units of length like centimeters, meters, or kilometers.
- Radius of a Circle. The radius of a circle is the length of the line segment joining the center of the circle to any point on the circumference of the circle.
- Diameter of a Circle. The diameter of a circle is a line segment that passes through the center of the circle and with endpoints that lie on the circumference of a circle.
Course: 2nd grade > Unit 8. Lesson 2: Equal parts of shapes. Equal parts of circles and rectangles. Equal parts of circles.
- You can achieve this to my knowledge atleast three different ways.
- Yes! A circle can be divided into any number of equal parts.
- Assuming you are talking about an equilateral triangle (a triangle with similar side lengths and angles for all three sides), you can split a trian...
- Yes it can be decided to any number equally or not equally infinitely
The diameter of a circle divides the circular region into two equal parts, each part is called a semicircular region. How many circles can be drawn to pass through two given points? From two given points, an infinite number of circles can be drawn, as shown in the figure below.
A circle is a 2d shape in which all the points in the plane are equidistant from a point which is called the center of the circle. Two circles with equal radii are congruent in nature. The diameter is the longest chord of a circle and it divides the circle into two equal parts.

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed shape, two-dimensional shape,curved shape. A few things around us that are circular in shape are a car tire, a wall clock that tells time, and a lollipop.
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. This distance is called the radius of the circle. Here, point P is the center of the circle.
Consider the circle with center P and radius r. A circle has an interior and an exterior region. All those points for which the distance is less than the radius of a circle lie in the interior of the circle. For example points P, Q, and R lie in the interior of the circle. All those points for which the distance is greater than the radius of a circ...
Semi means half, so semicircle is half a circle. It is formed by cutting a whole circle along a line segment passing through the center of the circle. This line segmentis called the diameter of the circle.
Quarter means one-fourth. So, a quarter circle is a quarter of a circle, formed by splitting a circle into 4 equal parts or a semicircle into 2 equal parts. A quarter circle is also called a quadrant.
The Radius of a Circle: A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. Radius = Diameter2 Diameter of a Circle: A line segment passing through the center of a circle, and having its endpoints on the circle, is called the diameter of the circle. Diameter = 2 × radius Circumference: The ...
Area of a circle: The area of a circle is the region enclosed inside the circle. The area of a circle depends on the length of its radius. Area = πr2 Circumference: The distance around the circle is the circumference of the circle. Circumference = 2πr The value of π = 3.14 or 227

Name 3 line segments that have the same length. 3. Name the secant. 4. Which two terms can be used to describe AB? Solution: 1. Radius 2. OA, OB, and OE 3. PQ 4. Diameter an...
The diameter of the circle divides it into two equal parts. Circles which have equal radii are congruent to each other. Circles which are different in size or having different radii are similar. The diameter of the circle is the largest chord and is double the radius.
Here we will learn about the different parts of a circle including how to identify the key parts of a circle from a diagram, how to identify the key parts of a circle from a definition and how to draw a circle with the different parts labelled e.g. the diameter of a circle.
