The plot below and to the right shows the first triangle. The small dots are vertices of all 100 triangles. The plot shows the original coordinates (rightmost of the triangles). Next, it is moved so the rightmost vertex is at (0,0). Then it is rotated counterclockwise so that the first cut is horizontal (from 0,0 to about -80,0). Finally, allowance is made for the cutting tool's radius. The green lines mark where the tool's center will travel when cutting the three edges.
