Use a Combination of Two Methods: The Projection Plane Replacement Method and the Cone Method Circumscribing the Sphere to Solve Complex Geometry Problems

Abstract

Geometry is a complex science and is widely used in daily life. Descriptive geometry is widely used in design works and construction of technical drawings for manufacturing. Many complex problems cannot be solved without finding a suitable auxiliary configuration. This article proposes a method to solve complex problems. This method will combine 2 methods of replacing the projection plane and the method of the cone circumscribing the sphere to solve the following complex problems.
