Concept Lectures

Session 01 : Circles: Definition, centre, radius, interior and exterior of a circle

Session 02 : Circles: Minor Arc, Major Arc, Central Angle

Session 03 : Circles: Chord, diameter, segment, major segment, minor segment, secant and tangent

Session 04 : Theorem: If two arcs of a circle (or of congruent circles) are congruent, then corresponding chords are equal.

Session 05 : Theorem: If two chords of a circle (or of congruent circles) are equal, then corresponding arcs are congruent.

Session 06 : Theorem: The perpendicular from the center of a circle to a chord bisects the chord

Session 07 : Theorem: The line joining the center and the mid-point of a chord is perpendicular to the chord.

Session 08 : How many circles can pass through one, two, three and more number of points on a plane?

Session 09 : Centre of the Circle lies on the angle bisector of angle between two equal chords - demonstration on GeoGebra

Session 10 : Centre of the Circle lies on the angle bisector of angle between two equal chords - Theorem Proof
