anonymous · Answer

all scalene triangles are acute?

anonymous · Answer

im going to assume it means draw diagonals between every vertex or point where lines meet

and say 

2 for quad
6 for hex
8 for octagon a

and ten for decagon.

otherwhise if you only draw one line from one to another vertex then its only ever one 2, (1 or zero triangles for the non quadrilateral options)
