A <strong>circle is a round two-dimensional plane figure, which is formed by the set of all those points that are at a fixed distance from a fixed point in the same plane<\/strong>. The circle looks similar to the letter \u201cO.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"376\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/03\/Parts-of-a-Circle-1.png\" alt=\"Real-life examples of circle\" class=\"wp-image-25729\" title=\"Real-life examples of circle\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/03\/Parts-of-a-Circle-1.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/03\/Parts-of-a-Circle-1-300x182.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\" eplus-wrapper\">Based on the shape and position, there are different parts of a circle in geometry that can be listed as <strong>center, radius, circumference, diameter, chord, arc, segment, tangent, secant, and sector<\/strong>.

Circle<\/h2>\n\n\n\n<p class=\" eplus-wrapper\">Any closed geometric figure has three regions. Since a circle is also a closed figure, it, too, has three regions. A circle has an inside, an outside, and an \u201con\u201d because we could be right on the circle. A point can lie in any of these three regions of the circle, namely the Interior region, the exterior region, or on the circle.<\/p>\n\n\n\n<h3 class=\"eplus-wrapper wp-block-heading\" id=\"16-interior-region-of-the-circle\">Interior Region of the Circle<\/h3>\n\n\n\n<p class=\" eplus-wrapper\">The region inside the circle is called its interior region and the point that lies in this region is called the interior point.&nbsp;<\/p>\n\n\n\n<h3 class=\"eplus-wrapper wp-block-heading\" id=\"17-the-exterior-region-of-the-circle\">The Exterior Region of the Circle<\/h3>\n\n\n\n<p class=\" eplus-wrapper\">The region outside the circle is called the exterior region of the circle and any point lying outside the circle is said to be in its exterior region.&nbsp;<\/p>\n\n\n\n<h3 class=\"eplus-wrapper wp-block-heading\" id=\"18-on-the-circle\">On the Circle<\/h3>\n\n\n\n<p class=\" eplus-wrapper\">Any point on the boundary of the circle is said to be on the circle.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"493\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/03\/Parts-of-a-Circle-14.png\" alt=\"Regions of a circle\" class=\"wp-image-25742\" title=\"Regions of a circle\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/03\/Parts-of-a-Circle-14.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/03\/Parts-of-a-Circle-14-300x239.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\" eplus-wrapper\">In this image,<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Point A is outside of the circle,<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Point B is inside of the circle, and<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Point C is on the circle.<\/p>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"19-facts\">Facts<\/h2>\n\n\n\n<ul class=\"eplus-wrapper wp-block-list\">\n<li class=\" eplus-wrapper\">The word \u201ccircle\u201d is derived from the Greek word \u03ba\u03c1\u03af\u03ba\u03bf\u03c2 (krikos), meaning \u201choop\u201d or \u201cring.\u201d<\/li>\n\n\n\n<li class=\" eplus-wrapper\">A circle is a curved shape with no edges.<\/li>\n\n\n\n<li class=\" eplus-wrapper\">The diameter is the longest distance between two points on a circle. Alternatively, we can also say that the diameter is the longest chord of the circle.<\/li>\n\n\n\n<li class=\" eplus-wrapper\">The measurement of the full arc of a circle is 360 degrees.<\/li>\n\n\n\n<li class=\" eplus-wrapper\">When we divide the length of the circumference by the length of the diameter, we get 3.141592654 . . ., which is the number $\\pi$ (Pi).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"20-conclusion\">Conclusion<\/h2>\n\n\n\n<p class=\" eplus-wrapper\">In this article, we saw some of the real-life examples of a circle, found out the definition of a circle, and learned about the different parts and regions of a circle.

circle of a polygon. It is the largest circle that fits inside the polygon and touches each side of the polygon only at one point. For a triangle, the center of an incircle is the point of intersection of three angle bisectors.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">A circumcircle or circumscribed circle is a circle that passes through each of the three vertices of a triangle. For a triangle, the center of the circumcenter is the point of intersection of the perpendicular bisectors of three sides.<\/p>\n\n<\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>What Are the Parts of a Circle?
