Important properties of Circle:- ◆ A circle lie on when plane divide into three parts, which are :- 1. Inner part of circle i.e. interior 2. Circle i.e. circumference 3. Outer part of circle i.e. exterior ◆ if chords of any circle subtends equal angles at the centre, then chords are equal. ◆ Equal chords of a circle subtends equal angles at centre. ◆ if two arcs of any circle are congruent, then their corresponding chords are equal. ◆ if two chords of a circle are equal, then corresponding arcs are congruent. ◆ The perpendicular from the centre of a circle to a chord bisects the chord. ◆ the line segment joining the centre of a circle to the midpoint of a chord is perpendicular to the chord. ◆ There is one and only one circle passing through three given points. ◆ Equal chords of a circle are equidistant from the centre. ◆ Chords of a circle which are equidistant from the centre. ◆ The angle subtended by an arc of a circle at the centre is double the a
