a leg of a right triangle can never be greater then the hypotenuse

this formula will tell you if it's a valid right triangle
[tex] {?}^{2} + {?}^{2} = {?}^{2} [/tex]
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.

THE STEPS:
[tex] {3}^{2} + { \sqrt{7}^{2} } = {4}^{2} [/tex]
[tex]9 + {2.65}^{2} = 16[/tex]
[tex] {2.65}^{2} = 7[/tex]
[tex]9 + 7 = 16[/tex]
ANSWER: [tex] \sqrt{7} [/tex]
