Question 695266
<font face="Times New Roman" size="+2">


If it is a right triangle, then the hypotenuse must be the longest side.  If *[tex \LARGE a] and *[tex \LARGE b] are the two shorter sides and the longest side is *[tex \LARGE c] and then if *[tex \LARGE c\ =\ \sqrt{a^2\ +\ b^2}] then the triangle is right.


So figure out which of 11, 5, and *[tex \LARGE \sqrt{146}] is the largest number, then calculate *[tex \LARGE a^2\ +\ b^2] where *[tex \LARGE a] and *[tex \LARGE b] are the two short sides.  If the result is 146, then the triangle is right, otherwise not.
