# If you have a SSA angle case with two possible solutions, how can you check both solutions to make sure they are correct?

Feb 14, 2015

Three numbers ($a , b , c$) can be the lenght of three sides of a triangle if and only if each of them is greater then the difference of the other two, and less of the sum of the other two.

I.E: (if $a > b > c$)

$a > b - c$,
$b > a - c$,
$c > a - b$;

and:

$a < b + c$,
$b < a + c$,
$c < a + b$.
