Thanks!

For those that are getting lost here just remember this is for a circumscibed circle...... not an inscribed as I have shown......

Now remember this trick:

1*9 is 9
2*9 is 18 is 1+8 or 9
3*9 is 27 is 2+7 or 9
4*9 is 36 is 3+6 or 9
5*9 is 45 is 4+5 or 9
6*9 is 54 is 5+4 or 9
7*9 is 63 is 6+3 or 9
8*9 is 72 is 7+2 or 9
9*9 is 81 is 8+1 or 9
10*9 is 90 is 9+0 or 9
11*9 is 99 is 9+9 or 18
12*9 is 108 is 10+8 or 18
13*9 is 117 is 11+7 or 18
14*9 is 126 is 12+6 or 18
