In the given figure O is centre of the circle of radius 5 cm, OP1CD, AB || CDAB 6 cm and CD = 8 cmDetermine PQCD0

Answer»

AP = 3{radius when perpendicular to chord bisects it }QC = 4{radius when perpendicular to chord bisects it }Applying pythagoras theoremIn OAPOP=4In OCQOQ=3OP=PQ+OQ4=PQ+3therefore PQ = 1
