to find it, we find the center point of each line and find the perpendicular line to it, the intersection is the circumcenter
first name the triangle
A=(-4,0)
B=(-4,-4)
C=(-1,-4)
the midpoint of AB is (-4,-2), the line perpendicular is y=-2
the midpoint of BC is (-2.5,-4), the line is x=-2.5
find the intersection
at (-2.5,-2)
at (-5/2,-2)
2nd one is answer
