Bored during the pandemic, Stan thought if three non-parallel lines make a triangle, how many triangles will four, five, six non-parallel lines make or, for that matter, as many non-parallel lines as you want.

The math is called combinatorics and the computer coding was done in Terrapin LOGO.  Read Stan’s article by CLICKING HERE.

And see a video of the computer showing the 10 triangles that arise from 5 non-parallel lines by CLICKING HERE.

By the way, Lindy thinks Stan is crazy.
