Question

8. Point O is the circumcenter of the triangle ABC shown below.

Answer 1

Answer:

Option B. perpendicular bisector of side AB

Step-by-step explanation:

we know that

The circumcenter is the intersection point of the perpendicular bisectors of a triangle  

so

In this problem

The circumcenter O is the intersection point of perpendicular bisector of side AB and perpendicular bisector of side BC

OA=OB=OC ------> the radius of the circle that passes through all three of the triangle's vertices.

therefore

Option B. perpendicular bisector of side AB
