could the following lengths form a trinagle? yes or no
\n" ); document.write( "1.) 7,5,2
\n" ); document.write( "2.) 9,12,13
\n" ); document.write( "3.) 12,2,19 \r
\n" ); document.write( "\n" ); document.write( "In a triangle the sum of any two sides must be greater than the third side.\r
\n" ); document.write( "\n" ); document.write( "1.) 2+5 is not greater than 7 so not a triangle.
\n" ); document.write( "2.) 9+12 > 13. 9+13 > 12. 12+3 > 9. Yes, it's a triangle.
\n" ); document.write( "3.) 12+2 is not greater than 9 so not a triangle.
\n" ); document.write( "
\n" );
