What is circle

A line segment that goes from one point to another on the circle's circumference is called a Chord. A circle has an inside and an outside of course! But it also has an "on", because we could be right on the circle. Example: "A" is outside the circle, "B" is inside the circle and "C" is on the circle. Example: You walk around a circle which has a diameter of m, how far have you walked? Style: MLA. English Language Learners Definition of circle Entry 1 of 2.

Just between us: it's complicated. Ask the Editors 'Everyday' vs. What Is 'Semantic Bleaching'? Its real-life examples include wheels, pizzas, orbit, etc. In geometry, a semicircle refers to the half of a circle. A chord is the line segment joining two points inside a circle.

As the diameter also having two endpoints in a circle so, it is the longest chord. All angles marked in the circle, subtended by the same chord are equal. The list of the different parts of a circle is tangent, chord, radius, diameter, minor arc, major arc, minor segment, major segment, minor sector, major sector.

The circumference of a circle is defined as the linear distance around it or we can say, if a circle is opened to form a straight line, then the length of that line will be the circle's circumference.

Terms related to Circles Center The fixed point in the circle is called the center. So, the set of points are at a fixed distance from the center of the circle.

Radius Radius is the fixed distance between the center and the set of points. Diameter Diameter is a line segment, having boundary points of circles as the endpoints and passing through the center.

So, logically a diameter can be broken into two parts: One part from one boundary point of the circle to the center And, the other part from the center to another boundary point. Arc of a circle The arc of a circle is a portion of the circumference. Minor arc: The shorter arc created by two points.

Major Arc: The longer arc created by two points. Sector of a circle: A Sector is formed by joining the endpoints of an arc with the center. On joining the endpoints with the center, two sectors will be obtained: Minor and Major. By default, we only consider the Minor sector unless it is mentioned otherwise. Semi-circle A semi-circle is half part of the circle or, A semi-circle is obtained when a circle is divided into two equal parts.

Important Properties of Circle — Lines Properties related to Lines in a Circle Chord A chord is a line segment whose endpoints lie on the boundary of the circle. Properties of Chord Perpendicular dropped from the center divides a chord into two equal parts. Tangent Tangent is a line that touches the circle at any point. Properties of Tangent Radius is always perpendicular to the tangent at the point where it touches the circle.
