[list=1][*]I started by creating a triangle of no particular size.[/*][*]I then used the perpendicular bisector tool with each edge of the triangle.[/*][*]The point the perpendicular bisectors met at is the circumcenter. This point is currently labelled as (3.5, 1.12) and is red.[/*][*]I then used the circle with center with a point tool to create a circle with the center at the circumcenter and the radius to the vertex.[/*][*]I connected the segments from the circumcenter to each vertex (these are in pink) and found the distance to be 3.68 for each.
