Minor Segment: The smaller part of the circle's segment is called the minor arc.Segment: The region enclosed between arc and chord is called the segment.In the following figure, red arc shows the major arc. Major Arc: The larger part of the arc is called the major arc.In the following figure, green arc shows the minor arc. Minor Arc: The smaller part of the arc is called the minor arc.Arc: A part of the circumference is called an arc.In the following figure, the line segment AB is a chord. It also divides the circle into two parts. Chord: A line segment whose endpoints lies on the circle is called chord.In the following figure, the line segment AB touches the circle at point P. Tangency Point: The point where the tangent line touches the circle is called tangency point.
In the following figure, the line segment AB is a tangent. Tangent: A line segment that touches the circle at a common point is called a tangent.In the following figure, O denotes the origin or center of the circle. Origin or Center: A point in the middle of the circle that has equidistant from all the points on the circle called the origin.It is denoted by The following figure, the green dotted line denotes the circumference. In other words, the arc length of the circle is called the circumference. Circumference: The distance around the circle is called the circumference.In the following figure, the line segment OA is the radius. In other words, the distance between the center and circumference is called the radius. Radius: A line segment that touches the center from one side and touches the boundary from another side, called the radius.In the following figure, the line segment AB is the diameter. Diameter: A line segment that passes through the center and touches the boundary of the circle at both sides, called the diameter.The following figure represents the shape of a circle.
The examples of the circle are wheel, coin, compact disc, etc. In other words, it is the locus of all points that have equidistant from the origin. Circle DefinitionĪ curved line that has the same distance from the center and connects at the point where it starts, called the circle. Along with this we will also learn the types of circle, properties, and formulas. In this section, we will learn the circle definition, diameter of a circle, circumference of a circle, and other parts of circle.
In geometry, a round-shaped figure is called a circle. In early education, we introduce with many geometrical shapes so that we can understand other subjects where the principles of circle apply. The theoretical importance of a circle applied in many subjects such as physics, astronomy, mathematics, etc. In geometry, the circle is the most important shape to learn.
