Definition: Points, Straight Lines, and Planes

Let $\mathcal P$ be an arbitrary non-empty set. The elements $A,B,C\ldots \in \mathcal P$ are called points.

Let $\mathcal L$ be an arbitrary non-empty set. We call the elements $a,b,c \ldots \in \mathcal L$ lines.

Let $\Pi$ be an arbitrary non-empty set. We call the elements $\alpha,\beta,\gamma \ldots \in \Pi$ planes.
