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.
