Question

The circumcircle of the Triangle with vertices at (0,0) , (m,0) and (0,n) is
a. x2 + y2 + mx + ny = 0
b. x2 + y2 - nx - my = 0
c. x2 + y2 - mx - ny = 0
d. x2 + y2 + nx + my = 0

Answer 1

The circumcenter of the triangle is the center of the circle that can be circumscribed about the triangle. Its center is equidistant from the vertices of the triangle.
