1. = isogonic adj.¹

ΚΠ

1857 W. Whewell Hist. Inductive Sci. (ed. 3) III. 52 The values of these elements at any given time..can be expressed by charts of the earth's surface, on which are drawn the isodynamic, isogonal, and isoclinal curves.

1857 W. Whewell Hist. Inductive Sci. (ed. 3) III. 54 The isogonal curves may be looked upon as deformations of the curves deduced by Euler from the supposition of two poles.

2. Having equal angles, equiangular.
