Rational (projective) Bezier curves are determined by three points on a plane and by positive weights ascribed to these points. It is known that such curves are either an arc of a parabola or an arc of an ellipse or an arc of a hyperbola. An equation for projective Bezier curves in barycentric coordinates is deduced in this paper. This equation depends on a parameter. A complete classification of considered curves depending on the parameter's values is given.
