Draw the diagonal from vertex 1 to vertex 6, from vertex 10 to vertex 7, from vertex 9 to vertex 5, from vertex 10 to vertex 6, from vertex 2 to vertex 9, from vertex 9 to vertex 6, from vertex 2 to vertex 5, from vertex 2 to vertex 4, from vertex 3 to vertex 8, from vertex 2 to vertex 10, from vertex 3 to vertex 1, from vertex 3 to vertex 6, from vertex 1 to vertex 5, from vertex 9 to vertex 4, from vertex 8 to vertex 10, and from vertex 7 to vertex 9. How many distinct pairs of diagonals meet at a perpendicular angle (within the polygon's interior or on its boundary)?
