Asquare is divided by its four lines of symmetry. triangles of different sizes are formed. how many total triangles are formed?

If you're only counting the smallest triangles, then 8.

If you're counting all possible triangles including triangles made of other triangles, then 16. Each diagonal gives 2, the combined diagonals give 4, and the unit triangles give 8 for a total of 2 + 2 + 4 + 8 = 16.

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
