C-08-Q055mediumsingle_mcq

The straight line joining the midpoints of two parallel chords of a circle—

ais parallel to one of the chords only
bpasses through the centre and is perpendicular to the chords
cis a tangent to the circle
dequals the radius

ব্যাখ্যা

The perpendicular from the centre bisects each chord, so the centre lies on the line through both midpoints; for parallel chords this line is perpendicular to both and passes through the centre.
