This problem comes in three levels of difficulty. Start
with the first and work your way up!
Level 1:
How many
noncongruent triangles
can be drawn on this 3 by 3 grid by connecting the dots?
| Example: |
 |
| NOTE: If you found the previous triangle, and then found this
triangle, it would be a rerun and it wouldn't count! (The two triangles are congruent!) |

Are you brave enough
(or a big enough math geek) to try a 6 by 6? I'm not! If you are, let me know what you get!
