@hanushanand Make a 2x2 square using the 9 dots, find no of rectangles. Each rectangle has 4 right triangles. Ans: 36?

Good ! Good! Much deserved halt , i would say! :D

thoda aur socho!! 
@hanushanand said:@YouMadFellow Sirjee! Starting with an Easy one:P.S.: No AnswersQ: Nine dots are placed on a piece of paper. Find the maximum number of right angled triangles which can be formed by joining any three dots. a) 18 b) 36 c) 40 d) 44 e) 48
44 hoga. QA Thread pe kara tha kabhi :P

3 x 3 ka grid banao.
9 rect. => 9*4 = 36 rt. Triangles.
Ab 8 aur right triangles banenge with 2 x 1 and 1 x 2 waale rectangles. :D

Hum padhai kar rahe hain baalak......DnD
Aur answer laane ke liya Stella hain na....Humari kyun zaroorat??
Kuch concepts confirm karo:
1. Number of rectangles in m X n grid = (m+1)C2 * (n+1)C2
2. Number of squares in n X n grid = (sigma)(n^2)
3. Number of squares in m X n grid = (sigma)[(m)*(n)]

3rd one me, Sigma m*n nhi hoga?? :O

2 hai ?
Tn = n^2 + 3n + 1 / (n^2) * ( n+1)^2 => n*(n+ 1) + 2n+ 1 / (n^2)*(n+1)^2
=> Tn = (1/n - 1/(n+1)) + ( 1/n^2 - 1/(n+1)^2))
