22??? Even the experts say 18.
I counted the triangles big and small and placed a dry marker spot on each (22)
There's some scalene triangles as well as equilateral and isosceles triangles.
Say what??? Are you sure those are names of triangles? Nevermind, they probably are.....I probably wasn't paying attention when it was taught in school. And wasn't great in math anyway. Funny part is, I worked in cashiering, bookkeeping and accounting in one form or another for over 20 years, but most of that was more basic math skills.
btw......the last time I counted, I found 25
The 3 small triangles at the very top, then extend the lines all the way to the bottom, gives 3 more, then each of the small spaces have 2 in each, then the one big one.
3+3+18+1=25
