A triangle has these sides. Will it be acute, right, obtuse or not possible? Show work to justify your answers.\r
\n" ); document.write( "\n" ); document.write( "1. 5,8,9\r

\n" ); document.write( "\n" ); document.write( "3. 3,5,11\r
\n" ); document.write( "\n" ); document.write( "4. 2,12,13
\n" ); document.write( "Call the longest side c, the others are a & b
\n" ); document.write( "If c >= a+b, it's not a triangle
\n" ); document.write( "If c <= |a-b| it's not a triangle
\n" ); document.write( "============
\n" ); document.write( "If the square of the longest side < sum of the squares of the other 2, it's acute.
\n" ); document.write( "------
\n" ); document.write( "If the square of the longest side = sum of the squares of the other 2, it's a right triangle.
\n" ); document.write( "------
\n" ); document.write( "If the square of the longest side > sum of the squares of the other 2, it's obtuse.
