Let $P$ and $Q$ be points in space.
Let $R$ be a point on $PQ$ dividing $PQ$ in the ratio:
- $PR : RQ = l : m$
where:
- $l$ is the length of the vector $PR$ in the direction of $PQ$
- $m$ is the length of the vector $RQ$ in the direction of $PQ$.
Then $PR : RQ$ is referred to as the position-ratio of $R$ with respect to the base-points $P$ and $Q$.
When $R$ is between $P$ and $QA$, the position-ratio is positive.
When $R$ is outside the segment $PQ$, the position-ratio is negative:
