true

amistre64 · Answer

can a chord be of length 0?

anonymous · Answer

No i don't think so, because if the length of the chord is zero then isn't there no chord?

amistre64 · Answer

dunno how rigorous the definintion of a chord is.  if its the line segment from a to b, and a=b,  ....  all depends on how a chord is defined.

amistre64 · Answer

if there is no stipulation that the end points have to be distinct, then a chord of length 0 is still a chord
