Easiest method: Determine the slopes.
\n" );
document.write( "Slope of AB: - .4
\n" );
document.write( "Slope of AC: - 2.5
\n" );
document.write( "Slope of BC: - 1
\n" );
document.write( "No 2 slopes are negative reciprocals of each other, so no 2 slopes are perpendicular, hence, this is NOT a right triangle \n" );
document.write( "

\n" );
