Question 1198202
<br>
You can do the formal proof, if a formal proof is needed.<br>
Since ON is perpendicular to CB and N is the midpoint of segment CB, triangles ONB and ONC are congruent, which makes segments OB and OC congruent.<br>
By the same argument, triangles OMA and OMB are congruent, making segments OA and OB congruent.<br>
So segments OA, OB, and OC are all congruent.<br>
