Christmas MT's answer to Ria's Secondary 3 E Maths Singapore question.
I presume their intended solution is for A to be the midpoint of the line segment OB.
Ria, do take note that line segment OB means the line which starts from O and ends at B or vice versa. It does not include any extrapolations/extensions from either end of the line.
