## Topics Covered in Exercise 9.2 class 9 Mathematics Questions

Ex 9.2 class 9 maths chapter 9 covers topics associated with perpendicular from the centre to a chord, equal chords and their distances from the centre and theorems.

 1 Perpendicular from the Centre to a Chord Theorem 9.3 Theorem 9.4 2 Equal Chords and their Distances from the Centre Theorem 9.5 Theorem 9.6
1. Perpendicular from the Centre to a Chord

There are two important theorems to understand this topic.

• Theorem 9.3: The perpendicular from the centre of a circle to a chord bisects the chord.

• Theorem 9.4: The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord.

1. Equal Chords and their Distances from the Centre - The length of the perpendicular from a point to a line is the distance of the line from the point.

In this section, you will study two important theorems related to the above topic.

• Theorem 9.5: Equal chords of a circle (or of congruent circles) are equidistant from the centre (or centres).

• Theorem 9.6: Chords equidistant from the centre of a circle are equal in length.
