%X Geometrical properties of complex Bezier curves of degree 2 which are definedon unit circular arcs, are discussed. The curve particularly has no singular pointsand has a possible inflection point, if the rotating directions of vertices of its co-ntrol polygon and its defined arc are the same. Furthermore, the curve is convex,if the inner- vertex is not close to each of end-vertices. A condition of spline curvesbased on such two complex Bezier curves with visual C~1 continuity is provided.
