Its spiral form is known as an equiangular spiral.

Its spiral form is known as an equiangular spiral.

A square is distinguished from other polygons by being foursided, equilateral, and equiangular.

For example, if all the equilateral triangles are all the equiangular, we know at once that all nonequilateral triangles are also nonequiangular.

Ah! you're found out, you _rectilineal antecedent_, and _equiangular_ old hag!

We may have a division consisting of mutually exclusive members, which yet involves a mixture of different bases, e.g. if we were to divide triangle into scalene, isosceles and equiangular.

In wellformed subjects, the anterior space is equiangular, the base being equal to each side; but according as the tuberosities approach the median line, the base becomes narrowed, and the triangle is thereby rendered acute.

Thus it is as true to say that 'All equiangular triangles are equilateral' as that 'All equilateral triangles are equiangular.'

For instance, in the particular case of equilateral triangles it is true to say, not only that 'all equilateral triangles are equiangular,' but also that 'all equiangular triangles are equilateral.'

Thus all equilateral triangles are equiangular triangles; but in one case they are named from the equality of their angles, and in the other from the equality of their sides.
