How many triangles are there in the pictured shape?
Answer 18
There are three triangles in the top section, but those can also be combined by adding their sections together for there to be 6. Then, by adding on lower sections, making the triangles bigger, you keep going, adding 6 more triangles from the middle section and 6 more when the bottom is included. The final section is the full-sized triangle, giving a total of 18.
