Definition

Let $AB$ and $PQ$ be line segments on a straight line such that $\tuple {AB, PQ}$ is a harmonic range.

Then $P$ and $Q$ are said to be harmonic conjugates with respect to $A$ and $B$.


Also known as

Two pairs of:

points $\set {A, B}$ and $\set {P, Q}$
rays $\set {OA, OB}$ and $\set {OP, OQ}$

which are harmonic conjugates are also known as a conjugate pair.

Harmonic conjugates can also be said to be apolar.
