Subject: circle with triangle
Unfortunately I lost the article. Someone horrorflickchick... asked about an

equation for a circle with given vertices.

The perpendicular bisectors of the sides of a triangle intersect at the same

point which is equidistant from the vertices of the triangle.

Find the perpendicular lines which intersect the midpoints of any two of the

sides; the lines so found intersect at a common point which is the center of

the circle. Use distance formula to find the vertex to center of circle

distance. Apply the appropriate values in a general or standard form equation

of a circle.
