Abstract: In the first note, consider a regular polygon. Its diagonals have a number of intersection points some of which happen to be collinear. An algorithmic method of discovering the collinearity is suggested. In the second note, a numeric measure of degeneracy of a triangle is suggested.
Keywords: diagonals of a regular polygon, collinearity of intersection points of diagonals, numerical criterion for the measure of elongation of a triangle.
