This has been recently "floating around", with the question being "How Many Triangles?":

I got the answer correct. Let's see how folks do.

I guess it was too easy. 18 it is.

 

[Mefisto]

Yeah. I got 17, read the comments, started losing my mind and then finally figured out I didn't count the, you know, triangle. The big one. With the smaller ones inside of it.

These were never my strong suit.

I saw 16.

I suspect that the two you missed are the ones that are 2/3 the size of the largest one.

I thought I caught those, but maybe a missed a couple.
