Points o, a, b lie on the same line. oa = 12 cm, ob = 9 cm. find the distance between the midpoints of segments oa and ob if: point o doesn’t lie on the segment ab .

1.5 cm

Step-by-step explanation:

In the figure attached,

OA = 12 cm and OB = 9 cm.

Let the mid points of OA and OB are P and Q.

Then we have to find the distance between P and Q.

Since P is the midpoint of OA so OP = = 6 cm.

and Q is the midpoint of OB so OQ = = 4.5 cm

Now PQ = OP - OQ

              = 6 - 4.5

              = 1.5 cm.

Distance between the midpoints of segments OA and OB is 1.5 cm.
