Usage of regard and treat

[Rikatang]

Regard - Consider in the stated way
Treat - To act or behave towards in the stated way

From dictionary I got the meaning of the above words. But I still do not understand the difference/usage of these words. In Cantonese, we use the word Represent or Equal. I think the words Regard or Treat are much appropriate but do not how to use these two words correctly.

Hope someone can help me. Thanks.
