Question

7. PQ and RS are two parallel chords of a circle whose
centre is O and radius is 10 cm. If PQ = 16 cm and
RS = 12 cm, find the distance between PQ and RS, if
they lie
(i) on the same side of centre O
(ii) on the opposite sides of the centre O.
​

Answer 1

Answer:

Complete step-by-step answer:

The radius of the circle is 10 cm. We draw a perpendicular line from the centre O on both PQ and RS. They cut the chords at points M and N respectively. So, ∠ONS=∠OMQ=90∘ as OM⊥PQ,ON⊥RS.
