Question

In the construction of the circumcenter, why do you only need to construct two perpendicular bisectors, and not all three?

Answer 1

because all 3 perpendicular bisectors meet at the same point

and you only need to lines to figure out any point of intersection

Answer 2

you could do all 3, but you'd be more efficient just picking 2 and find the intersection between them

Answer 3

*two lines*

Answer 4

thankyou :)
