Question

Which of the following statements is true of chords?

A chord is a line segments.A chord connects two points on a circle.A chord can be a radius of a circle.A chord can be a diameter of a circle.A chord divides a circle into two regions

Answer 1

All of those are true, except the one about the radius.  Because alternate definition of diameter uses the idea of chord. So, both ends of a chord have to be on the circle, but one end of a radius is at the center, so a radius can't be a chord.
