10ft.wide octagon shape, need to know what lenght and the angle cut to make. thank you\r
\n" ); document.write( "\n" ); document.write( "10ft x 10ft square to start
\n" ); document.write( "Angle size is rather simple too.
\n" ); document.write( "\"a=180%28s-2%29\" where s=number of sides(10) and a=total angular measurement
\n" ); document.write( "\"a=180%2810-2%29\"
\n" ); document.write( "\"a=180%288%29\"
\n" ); document.write( "\"a=1440\" divide by the number of angles
\n" ); document.write( "\"1440%2F10=144\" each angles measurement\r
\n" ); document.write( "\n" ); document.write( "Each side will be
\n" ); document.write( "\"l=h%28sqrt%282%29-1%29\" where h=hieght(10) and l=lengthof a side.
\n" ); document.write( "\"l=4.142135623730950488016887242097\"
\n" ); document.write( "
