To inscribe, bisect the angles of the triangle, where they intersect, is the center of the inscribed circle

To circumscribe, take the bisectors of the sides (perpendicular bisectors), where they meet, is the center of the circumscribed circle.

An interesting non common problem, is exoscribed circles. Google that.
