    Heres the equation you should use. \[a^{2} \times b ^{2} = c^{2}\]

    Lets say XY is "a" (25) and YZ = b (36)

    \[25^{2} \times 36^{2} = ?^{2}\]

    XY 25 mm and the length of side YZ is 36 if we imagine the two sides can fold, the smallest side would be

    if they completely close, the short side would be 11 if we open the sides as big as possible |dw:1444591405538:dw| the biggest the other side could be is 25+36= 61

    in other words, we the third side should be bigger than 11 but smaller than 61
