which of the followings sets of numbers could be the lengths of sides of a triangle?
\n" ); document.write( "1 mi, 9 mi, 10 mi
\n" ); document.write( "or
\n" ); document.write( "8 mi, 9 mi, 2 mi
\n" ); document.write( "or
\n" ); document.write( "1 mi, 9 mi, 11 mi
\n" ); document.write( "or
\n" ); document.write( "8 mi, 9 mi, 17 mi
\n" ); document.write( ":
\n" ); document.write( "The rule: \"the sum of the two smaller sides has to exceed the longest side\"
\n" ); document.write( "so only the 2nd one can be a triangle \n" ); document.write( "
\n" );
