Remarks

A triangle is the polygon of its three corners, and every question here is asked of that polygon, so a triangle and the polygon ToPolygon() makes of it give the same answers. The one thing a polygon cannot be is a triangle two of whose corners stand on each other, within the point tolerance: a polygon has three distinct corners at the least. Such a triangle has no width, and is asked as the segment between its two corners furthest apart, which is all of it there is. The walk along the edges is the one exception: it goes round the corners as they stand, A to B to C and back, so it reads no tolerance and a triangle of one point is walked too.

Each pair is worked out here one way only, the triangle first; the other shapes ask from their side by coming here, and turn a shortest segment round so that it leaves them.
