Use the Method of Spheres Inscribed in Cones to Solve Geometric Problems.

In geometry, there are problems that if solved by conventional methods are very long and sometimes impossible to solve. But if you find a suitable configuration, solving problems will be much simpler. The following is a method to find a sphere inscribed in a cone to solve some advanced problems in geometry. This method allows combining the distance problem with the angle problem into an easily solvable tangent problem. [ABSTRACT FROM AUTHOR]
