1989: Ephraim J. Borowski and Jonathan M. Borwein: Dictionary of Mathematics:

equiangular


Mistake

Any equilateral plane figure is also equiangular, and so is regular ...


Correction

As is demonstrated in Equilateral Polygon is not necessarily Equiangular, the rhombus is the simplest counterexample:

A rhombus is a parallelogram whose sides are all the same length.

Its angles may or may not all be equal.
