Q1 of 6 Page 116

In a circle with centre P, chord AB is drawn of length 13 cm, seg PQ ⊥ chord AB, then find l(QB).


We know that,


The perpendicular from the centre of a circle to a chord bisects the chord.


Therefore, it is given that,


AB=13 cm


PQ perpendicular to AB


|(QB) = AB/2


| (QB) = 13/2


| (QB) = 6.5 cm
