i dont think theres any shortcut here..you'll have to use distance formulla here.. 4 times here it is,,distance between (x1,y1) and (x2,y2) is sqrt[(x2-x1)^2 + (y2-y1)^2] hope this helps..

L(2, 2), M(8, -3) -2-2 -2-2 --------------- 0,0 6,-5; sqrt(36+25) sqrt(61) , good-ish

M(8, -3), N(-10, -6) 10 6 10 6 ------------------- 18, 3 0,0 sqrt(324+9) sqrt(333) = 18.248 , that one checks out too

N = -10,-6 -K = 4, -2 ------------ -6,-8; sqrt(36+64) sqrt(100) = 10 , that one looks off
