In this video, we dive into Theorem 4 of the Circles chapter (Class 9 Maths). We will prove that the line drawn through the center of a circle to bisect a chord is perpendicular to the chord.
This is the converse of Theorem 3, and understanding the relationship between the chord and the center is crucial for solving geometry problems in exams. I explain the proof step-by-step using triangle congruence so you can write it perfectly in your exams.
