Question

Line segment XY is a perpendicular bisector of segment AB, with the two segments meeting at point O. What is true about OB?

a. It has the same length as AO
b. It has the same length as OY
c. It has the same length as XO
d. It has the same length as XB

Answer 1

Since line segment XY is the perpendicular bisector of segment AB, it means that point O is the midpoint of segment AB. This implies that OB is equal in length to OA.

Therefore, the correct answer is:

a. It has the same length as AO.

Since O is the midpoint of AB, OB = OA.
