Using the perpendicular bisector theorem and Pythagoras rule, the length of line BG is 10 cm

The point G is the circumcenter, which is the intersection point of the three perpendicular bisectors.

The distances AG = BG = CG (the distances are equidistant from the point G)

Given that :

  • CF = 8 cm & FG = 6 cm

We can obtain CG ;

Using Pythagoras since the triangle is right angled;

CG² = CF² + FG²

CG² = 8² + 6²

CG² = 100

CG = √100

CG = 10 cm

Since CG = BG ;

BG = 10 cm

Therefore, BG is 10 cm.
