The sum of any two sides of a triangle must be greater than the third side (Triangle Inequality Theory). \n" ); document.write( "Let x=third side \n" ); document.write( "x+8cm must be greater than 11cm, so x>3cm \n" ); document.write( "8cm+11cm must be greater than x, so x<19cm \n" ); document.write( " |
