look:|dw:1444130099348:dw|

|dw:1444130175780:dw| use pythogorian theorem to count the sides of this triangle

|dw:1444130267064:dw|

4. AlexandervonHumboldt2

now use again the Pythagorean theorem to count the hypotenuse: 6^2+4^2=diagonal^2 36+16=diagonal^2 diagonal=$\sqrt{52}$=$\sqrt{2*2*13}$=$2\sqrt{13}$ thus the diagonal is $2\sqrt{13}$
