Isogonal, a mathematical term meaning "having similar angles", may refer to:
*
Isogonal figure
In geometry, a polytope (e.g. a polygon or polyhedron) or a Tessellation, tiling is isogonal or vertex-transitive if all its vertex (geometry), vertices are equivalent under the Symmetry, symmetries of the figure. This implies that each vertex i ...
or polygon, polyhedron, polytope or tiling
*
Isogonal trajectory
In mathematics, an orthogonal trajectory is a curve which intersects any curve of a given pencil of (planar) curves ''orthogonally''.
For example, the orthogonal trajectories of a pencil of ''concentric circles'' are the lines through their comm ...

Isogonal conjugate
__NOTOC__
In geometry, the isogonal conjugate of a point with respect to a triangle is constructed by reflecting the lines about the angle bisectors of respectively. These three reflected lines concur at the isogonal conjugate of . (Th ...

Isogonic line
A contour line (also isoline, isopleth, isoquant or isarithm) of a function of two variables is a curve along which the function has a constant value, so that the curve joins points of equal value. It is a plane section of the three-dimensi ...
