Re: Lets Count | 5 Nov, 2009

I think Mridula is correct.

I also can count upto 27 triangles.

Re: Lets Count | 5 Nov, 2009

Me too and here is the breakdown.

Lets define smallest possible triangle as Unit and so

1 Unit triangles = 16
4 Unit triangles = 7
9 Unit triangles = 3
All Unit triangles = 1

Re: Lets Count | 5 Nov, 2009

I missed on the 4 units ones, and I'd counted the big one :(

Congrats Mridula :cheers:

Re: Lets Count | 5 Nov, 2009

26, because there are only 6 4-unit ones.
16 size 1
6 size 4
3 size 9
1 size 16
total 16+6+3+1=26
