I Think I answered a question similar to this some days ago. Not sure who for though. Anyway there are a number of standard pencil, straightedge(ruler) and compass (for circles) constructions. These include bisecting an interval, bisecting an angle and constructing perpendicular lines.

Triangles are amazing shapes as they have numerous characteristics and properties. For example did you know that the triangle is the strongest plane shape? Sorry I digressed a bit.

Back to your question : The circumcircle of a triangle which is what you require is found by first constructing the perpendicular bisectors of each side. Actually you only require 2 of the 3 as they all intersect at the same point. This point is the centre of your circle and the radius is the distance from this point to the vertex of the triangle. I am a techno dinasaur so I can't show you a picture but I am sure you can find out how to do the simple construction of bisecting an interval(line). Note : be very accurate and precise as any small error will result in a final result which is not quite right and press lightly with your pencil. hope this helps!
