Trying to help with the difficulties of language ... Should we find a triangle, that meets the conditions, that has a side that is smaller then the smallest side of any other triangle that meets the conditions?

0 phil1882 Posted March 11, 2014 Report Share Posted March 11, 2014 ah i see where i made my mistake. i assumed height is always (1/2 base)^2 - other side^2 which isn't necessarily so. (only true for isosceles triangles or equilateral.) 6 25 29 is the best i could find. Quote Link to comment Share on other sites More sharing options...

Ahh the joys of the English language. Seems much more clear in my native language Quote Link to comment Share on other sites More sharing options...
