NCERT Solutions Class 9 Maths Chapter 10 Circles covers a brief introduction to the Circles, related terms, the angle subtended by a chord at a point, equal chords, and their respective distances from the center.
(i) Line segment joining the centre to any point on the circle is a radius of the circle. (ii) A circle has only finite number of equal chords. (iii) If a circle is divided into three equal arcs, each is a major arc. (iv) A chord of a circle, which is twice as long as its radius, is a diameter of the circle.
Solution: The centre of a circle lies in interior of the circle. A point, whose distance from the centre of a circle is greater than its radius lies in exterior. of the circle. (iii) The longest chord of a circle is a diameter of the circle. (iv) An arc is a semicircle when its ends are the ends of a diameter.
