説明
CAD faculties were used for the generation of triangles from their three angle-bisectors, with their lengths only given. At this time we account for its theoretical basis, attempts of example drawing in point and measurement on accuracy of those solutions. Relatedly, a new method is introduced for executing on the CAD screen the arithmetic four rules used in the current geometric construction. And, as to any side and angle-bisector of an isosceles triangle, an approximately relationship between both their lengths is provided in equation form. The accuracy in the present onscreen drawing solution has proved to be within 0.04 and 0.4% respectively in constructing isosceles triangles and in using the above equation. How to improve such accuracy and extendedly apply our system to scalene triangles are left for further consideration.
