One Answer on this Question

  1. Since, there are 10 points on the circle and to draw a chord we need to connect any two points on the circle to make it a straight line, which implies that the number of chords = No of lines connecting any two points out of the 10 points

    = 10C2 = 10*9/2 = 45 chords.
