Question

proof of all theorems of circles of class 9​

Answer 1

Answer:

Circle theorem includes the concept of tangents, sectors, angles, the chord of a circle and proofs. A circle is the locus of all points in a plane which are equidistant from a fixed point. The fixed point is called the centre of the circle, and the constant distance between any point on the circle and its centre is called the radius. The perimeter of a circle is known as the circumference and the area occupied by a circle in a plane is its area. The tangent is perpendicular to the radius, at any point of a circle, through the point of contact. Let us learn more about the circle and its theorems here.
