Hint: Minor arc AB = minor arc CD. Subtract minor arc BD from both sides.
b.(given in the picture).
Cd are equal chords of a circle wuth centre O and AD is a diameter .If angle DEF =110 find angle FAB?
10. In Fig.13.35, CD is the perpendicular bisector of the chord AB. If AB = 2 cm and CD = 4 cm, calculate the radius of the circle. (SC)
(i) AP = CP,
(ii) BP = DP

Q.8. In the given figure, AB and CD are two equal chords of a circle, with centre O. If P is the mid-point of chord AB, Q is the mid-point of chord CD and , find .
Q3. Two points A and B are given. Find the set of feet of the perpendiculars dropped from the point A onto all possible straight lines passing through the point B.
32. To prove SQ = SR
SP is bisector of RPT and PQRS is a cyclic quadrilateral.
