Show that $\pmb{\hat{\beta}}$ and $\pmb{\hat{\sigma^2}}$ are independents and $SSRes$ and $SSR$ are independents too

I can't show that $\pmb{\hat{\beta}}$ and $\pmb{\hat{\sigma^2}}$ are independents and that $SSRes$ (residuals) and $SSR$ (regression) are independents too.

I need to show this in matrix notation.
