In English, the word *that* can be used as emphasis for adjectives (with some prior context). For example:

> 
> I’m not **that** rich.   
> 
>  She’s not **that** dumb.   
> 
>  Is he **that** mad? 
> 
> 
> 

How can we use the same kind of emphasis in German?

Edit:

I know *that* can be translated as *das, dass and diese.* However, those aren’t what I’m looking for. Also, the *that* here refers to some level of the adjective that’s previously stated. It can be used without *not* too, and I’m not sure about *so* (German) since it doesn’t feel like what I’m looking for exactly.

Another example:

> 
> Is he so smart that he got a Nobel Prize?  
> 
>  Yes, he’s **that** smart.
> 
> 
>
