Answer 1

16. Circle F

• You name a circle using the center.

17. BF

• A radius connects the center to a point on the circumference of the circle.

18. CD

• A chord is a segment connecting two points on the circumference of the circle.

19. BE

• A diameter is a segment that passes through the center while also connecting two points on the circumference of the circle.

20. FA

• See 17 and 19.

Answer 2

16. F

17. FA

18. CD

19. BE

20. FA

Explanation:

Question 16

A circle is named by its center.

The center of the given circle is F, therefore the name of the given circle is F.

Question 17

The radius of a circle is a straight line segment from the center to the circumference.

Therefore, the radii of the given circle are:

• FA, FB and FE.

Question 18

A chord is a straight line segment joining two points on the circumference of the circle.

Therefore, the chords of the given circle are:

• BE and CD.

Question 19

The diameter of a circle is the width of the circle at its widest part. It is a straight line segment that passes through the center of the circle and whose endpoints lie on the circumference.

Therefore, the diameter of the given circle is:

• BE.

Question 20

As the diameter is BE, it contains the radii FB and FE.

Therefore, the radius that is not contained in the diameter is:

• FA.
