I'm not sure you could say there are wrong answers here, OP. How would you know how many triangles they see unless you're Ayn Rand's ghost?
(Foxpup wins)
True, it is subjective and all answers are "Technically" correct. (Some people may see less/more then you or me) But if if you want to know how many triangles the image has without repeating then here is the simple answer: (27)
However, one could also argue the
title contains the word "triangle" as an additional one. (27+1)
For those looking for a more complex solution to the puzzle take a look at this answer.

correctly. (Kudos to you to Kluge!)
That's incorrect.
