Answer:
D. GH = FH because FG is perpendicular to the radius of a circle A.
Explanation:
A circle has different parts which include but no limited to; diameter, chord, radius, segment, sector, circumference etc. This, it can be observed that FG is a chord on circle A, and a chord is always perpendicular to the radius of the circle that bisects it. This implies that FG has been bisected into two equal haves of FH and GH by the radius AH.
Therefore, since FG is at a right angle to AH, then it is true that GH = FH. So that the appropriate answer to the given question is option D.
