Author Topic: How many triangles?  (Read 2865 times)

A poster very similar to this hangs in the back of my math room. I can't for the life of me figure out how many there are exactly. Thoughts?








He (My math teacher) said it was more than 50.

I got 13 triangles.
Still confused.

He (My math teacher) said it was more than 50.
Eh?
Unless your math teacher, or someone esle can proove it, im calling bull.





For those having trouble seeing more than ~12, look at some of the more difficult triangles to see.
