Answer:
see explanation
Explanation:
(a)
The diameter is a line connecting 2 points on the circle and passes through the centre, thus
GF is the diameter
(b)
A radius is a segment joining the centre to a point on the circle, thus
EG, EF and EH are radii of the circle
(c)
A chord is a segment joining 2 points on the circle, thus
JI is a chord
(d)
EH is one half the diameter, thus
GF = 8 units, hence EH = 8 ÷ 2 = 4 units
