Are there more Episodes mentioning triangles?

Question

Good day!

I'm a teacher from Germany and want to start with the new topic "triangles".

To have a more interesting beginning into this part I would like to show a short part (or more if there are some more) of the simpsons.
I googled a lot but only found the Episode with the Kissinger glasses. That is way to much for 12 year old Children, that would be perfekt for my 9th graders. But now they are in 10th grade and won't need it anymore :(

So, do you have any ideas where i can find allusions to tiangles?

 

Thanks a lot!!

In the episode "Please Homer, Don't Hammer 'Em," Bart plays a terrible arcade game in the rundown mall (Triangle Wars? I think?) with triangles on the screen that disappoints him.
