The critical theorems of Class 9 Chapter 10 Circles are listed below.

1. Theorem: Equal chords of a circle subtend equal angles at the centre.
2. Theorem: This is the converse of the previous theorem. It implies that if two chords subtend equal angles at the centre, they are equal.
3. Theorem: Equal chords of a circle are equidistant from the centre of a circle.
4. Theorem: This is the converse of the previous theorem. It states that chords equidistant from the circle's centre are equal in length.
5. Angle subtended by an arc at the centre of a circle is double that of an angle that arc subtends at any given point on the circle.
6. Theorem: Angles formed in the same circle segment are always equal in measure.
