Mathematics
Centre
वृत्त का केंद्र
In Class 9 Mathematics, this topic introduces the centre of a circle as the fixed point that is equidistant from every point on its circumference. Students learn how the centre connects to radii, diameters and chords, and how it helps identify key properties of circles. They use these ideas to understand why the perpendicular from the centre to a chord bisects the chord and how equal chords relate to equal distances from the centre, supporting clear geometric reasoning in the Circles chapter.
