## 1.In the figure, OD is perpendicular to chord AB of a circle whose centre is O. If BC is 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 ï¿½xï¿½ 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. If BC is a diameter, show that AC || OD and AC = 20D.            Hint: ∴ OD ⊥ AB               therefore; D is the mid-point of AB. 9.   If two intersecting chords of a circle make equal angles with the diameter passing through their point of intersection, prove that the chords are equal. 10.   Show that the angles in the same segment of a circle are equal.
