statement: IF two angles are adjacent, THEN they have common vertex, and a common side.
\n" ); document.write( "converse: IF two angles have a common vertex, and a common side, THEN they are adjacent angles.\r
\n" ); document.write( "\n" ); document.write( "Both original statement, and converse are true( in this case only, not usually)
\n" ); document.write( "therefore we can write a biconditional,\r
