 a) List three segments that are radii of this circle. 
 b) List a segment that is a diameter of this circle. 
 c) List a chord of this circle that is not a diameter.

Answer 1

(a)|MA|, |MB| and |MC|

(b) |BD|

(c) |BC|

Explanation:

An adapted diagram of this question is attached. You can vary the labelled letters as required.

Definition

• A radius is a line drawn from the center of a circle to its circumference.
• A segment is a line that connects two points.
• A diameter is a chord which passes through the center of the circle.
• A chord 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|
