An adapted diagram of this question is attached. You can vary the labelled letters as required.
<u>Definition</u>
- A <u>radius </u>is a line drawn from the center of a circle to its circumference.
- A <u>segment </u>is a line that connects two points.
- A <u>diameter</u> is a chord which passes through the center of the circle.
- A <u>chord</u> is any line joining two points on the circles' circumference.
By these definitions:
(a)Segments that are radii of this circle.
We have: |MA|, |MB| and |MC|
(b)Segment that is a diameter of this circle.
|BD|
(c)A chord of this circle that is not a diameter.
|BC|
