Answer:
What is a Circle in Geometry?
1.The word ‘circle’ is derived from a Greek word that means ‘hoop’ or ‘ring.’ In geometry, a circle is defined as a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center.”
Radius : a straight line from the centre to the circumference of a circle or sphere
Chord:a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle.
