In two concentric circles a chord $AB$ of the outer circle meets the inner circle at $C$ and $D$ . Then—

a $AB = CD$
b $AC = BD$
c

ব্যাখ্যা

The perpendicular from the common centre bisects both chords, so it bisects $AB$ at its midpoint and $CD$ at the same point; subtracting the equal inner halves from the equal outer halves gives $AC = BD$ .
