A skew "'isogonal apeirogon "'alternates two types of edges with various Frieze group symmetries.

A semi-regular ( or Archimedean ) tessellation uses more than one type of regular polygon in an isogonal arrangement.

Quasiregular polyhedra are isogonal and isotoxal, but not isohedral; their duals are isohedral and isotoxal, but not isogonal.

Quasiregular polyhedra are isogonal and isotoxal, but not isohedral; their duals are isohedral and isotoxal, but not isogonal.
25.
There are also isogonal icositetragrams constructed as deeper truncations of the regular dodecagon { 12 } and dodecagram { 12 / 5 }.

Deeper truncations of the square can produce isogonal ( vertex-transitive ) intermediate star polygon forms with equal spaced vertices and two edge lengths.
29.
Let P and P ` be isogonal conjugates with respect to the incenter I of triangle ABC, and & alpha; a given constant.

As isogonal conjugation is a function, it makes sense to speak of the isogonal conjugate of sets of points, such as lines and circles.
