You can put this solution on YOUR website!
if the exterior sides are opposite rays, then they form a straight line.
\n" ); document.write( "as such, the angles will always be supplementary.
\n" ); document.write( "this means their sum will always be 180 degrees.
\n" ); document.write( "if the angles were complementary, their sum would always be 90 degrees.
\n" ); document.write( "that will never happen if they are opposite rays.\r
