Let $A$ and $B$ be points on a straight line.
Let $P$ and $Q$ lie on $AB$ such that $P$ is on the line segment $AB$ while $Q$ is outside the line segment $AB$.
Let $P$ and $Q$ be positioned such that the cross-ratio $\set {A, B; P, Q}$ forms a harmonic ratio:
- $\dfrac {AP} {PB} = -\dfrac {AQ} {QB}$
Then $\tuple {AB, PQ}$ are said to be a harmonic range.
