WebA few important theorems are: Theorem 1: Equal chords of a circle subtend equal angles, at the centre of the circle. Converse of Theorem 1: If two angles subtended at the centre, by two chords are equal, then the chords are of equal length. Theorem 2: The perpendicular to a chord, bisects the chord if drawn from the centre of the circle.

WebIn Chapter 10 Class 9 of NCERT, Circles, Theorems are extremely important, we have provided detailed explanation of the theorems of circles as well as NCERT Solutions of all questions and examples. The basics - What is a circle, radius, diameter, arc, sector, segment, chord. Equal chords subtends equal angle at the center, and its converse.
WebCircle 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.
