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 13 Report post 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. Share this post Link to post Share on other sites

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? yes, when you phrase it that way, i see how complex it sounds. Ahh the joys of the English language. Seems much more clear in my native language Share this post Link to post Share on other sites
