CLASS-9 chapter-circle HOTS 1.    In the figure, OD is perpendicular to chord AB of a circle whose centre is O. If BC is a diameter; prove that CA = 2OD. 2.    l is a line intersecting two concentric circles having common centre O, at A, B, C and D. Prove that AB = CD. 3.    AB and CD are equal chords of a circle whose centre is O. When produced, these chords meet at E. Prove that EB = ED. 4.    If O be the centre of the circle, find the value of �x� in each of the following figures. 5.    Prove that equal chords of a circle subtend equal angles at the centre. 6.    The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord. Prove it. 7.    Prove that equal chords of a circle (or congruent circles) are equidistant from the centre (or centres). 8.    In the figure, OD is perpendicular to the chord AB of a circle with centre O.
