Given that vectors $\overrightarrow{a}$ and $\overrightarrow{b}$ are not collinear, $\overrightarrow{AB} = λ\overrightarrow{a} + \overrightarrow{b}$, and $\overrightarrow{AC} = \overrightarrow{a} + μ\overrightarrow{b}$ ($λ$, $μ ∈ R$), find the condition for points $A$, $B$, and $C$ to be collinear.
