A polygon can be separated into triangles by drawing all possible diagonals from one vertex. How many triangles does a 3 sided figure have? A 4 sided? 5? 6? 7? 8? What is the pattern?
Please help or explain to me how to do this. I really don't understand. When I did it but drawing all the triangles out, I don't think I counted right because there is no pattern...
