We have been studying the various properties and terms associated with circles. Using these basic concepts we will now learn some interesting facts about chords of a circle by proving some theorems.
In this session we have covered the following theorems in a very logical and easy manner in just 11 minutes:
1) Equal chords of a circle subtend equal angles at the centre.
2) If the angles subtended by the chords of a circle at the centre are equal, then the chords are equal.
3) The perpendicular from the centre of a circle to a chord bisects the chord.
4) The line drawn from the centre of a circle to bisect a chord is perpendicular to the chord.
5)There is one and only one circle passing through the three non-collinear points.
Understanding these theorems will help you in solving various problems related to circle.
