Triangles are the strongest structure in the world - most bridges etc include triangular metal parts to strengthen the bridge. I reccommend that you somehow create many triangles and support your textbook on top of these triangles.
two right triangles
if you need to know how many triangles are in a polygon ... just take the number of its sides and subtract for example. nonagon has 9 sides so it will be 9-2=7 so, a nonagon has 7 triangles
They are Similar triangles if they have the same angles. it they are exactily the same they are Equaltrial.
there are 27 triangles in a triangle
There are 15 triangles in a 17-agon
15 triangles!!!!!!!!!!

depends on what size triangles and what kind of triangles?
