Which one doesn't belong?

Depends, either option 3 or 4. I would say 4

Step-by-step explanation:

1,2,3 have the same line, just rotated, and 4's line is different

1,2,4 all start at the origin, tho

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
