If two chords of a circle are equal, then the perpendicular distances from the centre to those chords are—

aunequal
bequal
czero
dproportional to the radius

ব্যাখ্যা

Equal chords are always the same distance from the centre; this is the content of Theorem 18, proved by the congruence of the two triangles formed by the radii and perpendiculars.
