To give a definition of an angle is not possible,
An angle
meaning by a definition a definition
it differentiates: namely an indication of the genus
of which it is a species, and some circumstance belonging
to it, in respect of which it differs from
ever other species of that same genus: in a word, word,
you can not say of an angle that it is — any
thing.
The The only
form of words by means of which it is capable of
being expounded is a para + paraphrasis

leaf.
Nor even by a paraphrasis paraphrasis can a complete conception
of it be afforded, without the help of some additional observations.
To every For conveying a clear and complete conception of an
angle relation must be had to a circle; that is to say either immediately
or through the medium of some other figure, by means of
the relation which that figure has to a circle; that is to
say, either a polygon inscribed in a circle, or a polygon by
which the circle is circumscribed. By that this means, and
no other can you divide it into parts: such as those
s degree, by which word, by or must
a stop. The subject matter to which the word degree is
applies is in the first instance not the angle but the
circle Of these degrees into which a circle has at (so it has happened)
circle. For a circle number of the degrees is
been divided is 360 360: and this and no other is the number which for
this purpose has
by every body been employed
360. In no angle can there be more than, nor even
quite as much as half the number of these degrees namely
179 (a) (a) for when the number of these degrees arrives at the
180, the form of what is called a sector (it would
be more expressively called a wedge) ceases: it gives place to
that of a
semicircle.
