The distance between the midpoints of segments OA and OB is 1.5 cm.
Given that, points O, A, and B lie on the same line. OA = 12 cm, OB = 9 cm.
We need to find the distance between the midpoints of segments OA and OB.
A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments. The midpoint of a line segment is the point on a segment that is at the same distance or halfway between the two ending points.
Let X be the midpoint of OA and Y be the midpoint of OB.
Now, the midpoint of OA is OX=AX=OA/2
=12/2=6 cm
Then, the midpoint of OB is OY=YB=OB/2
=9/2=4.5 cm
The distance = 6-4.5=1.5 cm
Therefore, the distance between the midpoints of segments OA and OB is 1.5 cm.
