I want to make an AC dimmer and the circuit diagram from the instructables uses a bridge rectifier which is in DIP package and rectangle in shape and the rectifier which I have is round one, so how can I connect it in the circuit replacing the rectangular one?

If you want to keep the modifications of the circuit board to a minimum I would recommend to get another DIP socket (6 pins), remove the unneeded pins, cut the wires of the round rectifier to an appropriate length and solder the them to the DIP socket. Finally plug the DIP socket to the PCB. Be sure to watch for the proper pinout though, but since everything is labeled that should be quite easy.
Always assuming that the current and voltage ratings of the new rectifier are appropriate. As pointed out by Spehro Pefhany, the voltage rating of the W005M (round) is lower than the rating of the DF02 (DIP), so this needs to be checked against the supply voltage before changing the parts.
They're clearly marked with ~, ~, + and -. There is no difference between the two ~ terminals. You can probably bend the leads of the WOxx to fit but it won't be pretty.
