Question

in a circle,ab and cd are two parallel chords with centre o and radius 10 cm such that ab=16 cm and cd=12 cm determine the distance between the two chords?

Answer 1

construct a circle firstly then draw two line parallel to center o

from theourm we know that perpendicular drawn on chord bisect the chord into 2 equal part
so
let's supposed there is a point on Ab which divides ab.

so in ∆OAU (we suppose point u on Ab)
OA²=ou²+ua²
where oa is radius 10 cm similarly repeat the step and you get your answer
