Circle: A circle is a collection of all points in a plane which are at a constant distance from a fixed point. Centre: The fixed point is called the centre. Radius: The constant distance from the centre is called the radius. Chord: A line segment joining any two points on a circle is called a chord.
Circle – A circle is a locus of all the points which are equidistant from a given point. The formula for the circle is (x-h)2 + (y-k)2 = r2 Drawing a circle. Parts of a circle – Annulus – the area bounded by who concentric circle. Arc – it is a connected curve of a circle. Sector – an area bounded by two radii and an arc. Segment – an area bounded by a chord and an arc of a circle is known as a segment. A segment does not have a center. Centre – Midpoint of a circle. Chord – a line whose endpoints lie on the circumference of the circle. Diameter – a line segment whose endpoints lie on the circumference of the circle and also passed through the center of the circle. Radius – the shortest distance between the center and circumference of the circle. Secant – a straight line that cuts the circumference of the circle at two points. it is an extended chord. Tangent of a circle – tangent is a line that touches the circle at a single point and tangency is the point where the tangent meets the circle. A tangent is always perpendicular to the radius of the circle.Read more on Sarthaks.com - https://www.sarthaks.com/2866402/ncert-solutions-class-10-maths-chapter-10-circles
