§. Figures, regular
and irregular.
1.
Figures are
1. Regular
2. Irregular
2.
Irregular most: human
bodies in particular.
3.
Regular very few. These
are the products either
of
1. Nature — or
2. Art.
4
Figures produced by Art
— Examples
1. A board
2. A table
3. A child's marble.
5.
Of irregular figures,
the mode of explanation
is — by their relation
to regular ones.
6.
Irregular figures produced
by Nature — Examples
1. A man
2. A tree
3. A stone
7
Mode of explaining irregular
figures by division
into regular
ones.
8.
Mode of explaining
complex figures, division
into simple
9.
Mode of dividing an irregular
into regular figures —
Example 1. A field — having sides
more than one divided into
trilateral figures called
triangles — more than one.
10
☞ Here exhibit an
example of this sort
from Euclid's Elements.
10.
Mode of distinguishing
figures from figures is
by their boundaries
11.
The boundaries of a body
are its surfaces.
12.
The boundaries of a
surfaces are its lines
13
The boundaries of a
line are its points.
14.
Surfaces a body may have
in any number less
than three: they are
termed its sides.
15.
Name generally given
to a three-sided figure
of one surface a
triangle.(a)
15(a). Note here the
irregularity of the denominations —
1. Triangle
2. Quadrilateral (figures).
3. Pentagon
4. Hexagon &c.
16.
Number of boundaries
a line can have, two
and no more.
17.
A trilateral a triangle
should have been
called.
18
Sorts of lines two
1. Right or say straight
2. Curve.
19
A straight line never
changes its direction —
Were it to change its
direction it would be
no longer one line,
but would consist of
two straight lines
containing between
them an angle.
20.
A curve line is
continually changing
its direction: every
part being taking
with the next succeeding
part a direction
different
from that which it
took with the next
preceding part.
