Polygons and triangles correspondence after triangulating a mesh in Blender

One of the methods for mesh analytics is exploring its triangulated geometry. For example, such exploration is used when searching for polygons that overlaps in the mesh itself or in its UV. In order to return the result obtained after analyzing the triangulated mesh back to the original mesh, we need to know the exact correspondence between the original polygon and the triangles created from it.
