X = NUMBER OF SIDES OF ONE POLYGON
\n" ); document.write( "X+3 = NUMBER OF SIDES OF OTHER POLYGON
\n" ); document.write( "NUMBER OF DEGREES IN ONE POLYGON IS EQUAL TO 180 * (X-2)
\n" ); document.write( "NUMBER OF DEGREES IN OTHER POLYGON IS EQUAL TO 180 * (X-2+3)
\n" ); document.write( "DIFFERENCE IN DEGREES BETWEEN THE 2 IS:
\n" ); document.write( "180 * (X-2+3) MINUS (180 * (X-2))
\n" ); document.write( "SIMPLIFY THIS TO GET:
\n" ); document.write( "180 * (X+1) MINUS (180*(X-2))
\n" ); document.write( "SIMPLIFY FURTHER TO GET:
\n" ); document.write( "180*X + 180 MINUS (180*X - 360)
\n" ); document.write( "SIMPLIFY FURTHER TO GET:
\n" ); document.write( "180*X + 180 MINUS 180*X + 360
\n" ); document.write( "COMBINE LIKE TERMS TO GET:
\n" ); document.write( "+540
\n" ); document.write( "THE POLYGON WITH 3 MORE SIDES WILL HAVE 540 MORE DEGREES IN ITS SUM THAN THE POLYGON WITH 3 LESS SIDES.
\n" ); document.write( "AN EXAMPLE:
\n" ); document.write( "POLYGON WITH 3 SIDES IS EQUAL TO A SUM OF (3-2)*180 = 180
\n" ); document.write( "POLYGON WITH 6 SIDES IS EQUAL TO A SUM OF (6-2)*180 = 720
\n" ); document.write( "DIFFERENCE BETWEEN THE 2 IS 720 - 180 = 540\r
