We know that in any triangle, the sum of any two sides must always be greater than the third side.
\n" ); document.write( "We just need to check if this is true using these sides:)\r
\n" ); document.write( "\n" ); document.write( "\"11%2B15=26%3E21\"
\n" ); document.write( "\"11%2B21=32%3E15\"
\n" ); document.write( "\"15%2B21=36%3E11\"\r
\n" ); document.write( "\n" ); document.write( "Since all of the sums are greater than the third side, it is possible to make a triangle with these three sides.
