そう こう どう Ｅｘｐｌａｉｎ

[kentaku_sama]

Recently,I learned about そう can someone give me some sentences and info with translation using そう　こう and　どう.

I knew dou was "how" but I wasn't sure on how to use it.

A textbook, or a grammar reference book like Dictionary of Basic Japanese Grammar, or even Tae Kim's site, will answer this kind of question.

These are my opinion.
これ　＝this 　　　　 　 →　こう　＝this way　
それ　≒it, that 　 →　そう ≒so, that way
(それ points what is located in nearer distances between here and that.)
あれ ＝that →　ああ　＝that way
どれ　＝what, whitch →　どう　＝how

これはどうやって使いますか。
それはこうやって使います。
なるほど、これはそうやって使うのですね。
