Geometric \Ge`o*met"ric\, Geometrical \Ge`o*met"ric*al\, a. [L.
geometricus; Gr. ?: cf. F. g['e]om['e]trique.]
1. Pertaining to, or according to the rules or principles of,
geometry; determined by geometry; as, a geometrical
solution of a problem.
[1913 Webster]
2. (Art) characterized by simple geometric forms in design
and decoration; as, a buffalo hide painted with red and
black geometrical designs.
Syn: geometric.
[WordNet 1.5]
Note: Geometric is often used, as opposed to algebraic, to
include processes or solutions in which the
propositions or principles of geometry are made use of
rather than those of algebra.
[1913 Webster]
Note: Geometrical is often used in a limited or strictly
technical sense, as opposed to mechanical; thus, a
construction or solution is geometrical which can be
made by ruler and compasses, i. e., by means of right
lines and circles. Every construction or solution which
requires any other curve, or such motion of a line or
circle as would generate any other curve, is not
geometrical, but mechanical. By another distinction, a
geometrical solution is one obtained by the rules of
geometry, or processes of analysis, and hence is exact;
while a mechanical solution is one obtained by trial,
by actual measurements, with instruments, etc., and is
only approximate and empirical.
[1913 Webster]
Geometrical curve. Same as Algebraic curve; -- so called
because their different points may be constructed by the
operations of elementary geometry.
Geometric lathe, an instrument for engraving bank notes,
etc., with complicated patterns of interlacing lines; --
called also cycloidal engine.
Geometrical pace, a measure of five feet.
Geometric pen, an instrument for drawing geometric curves,
in which the movements of a pen or pencil attached to a
revolving arm of adjustable length may be indefinitely
varied by changing the toothed wheels which give motion to
the arm.
Geometrical plane (Persp.), the same as Ground plane .
Geometrical progression, proportion, ratio. See under
Progression, Proportion and Ratio.
Geometrical radius, in gearing, the radius of the pitch
circle of a cogwheel. --Knight.
Geometric spider (Zo["o]l.), one of many species of
spiders, which spin a geometrical web. They mostly belong
to Epeira and allied genera, as the garden spider. See
Garden spider.
Geometric square, a portable instrument in the form of a
square frame for ascertaining distances and heights by
measuring angles.
Geometrical staircase, one in which the stairs are
supported by the wall at one end only.
Geometrical tracery, in architecture and decoration,
tracery arranged in geometrical figures.

Progression \Pro*gres"sion\, n. [L. progressio: cf. F.
progression.]
[1913 Webster]
1. The act of moving forward; a proceeding in a course;
motion onward.
[1913 Webster]
2. Course; passage; lapse or process of time.
[1913 Webster]
I hope, in a short progression, you will be wholly
immerged in the delices and joys of religion.
--Evelyn.
[1913 Webster]
3. (Math.) Regular or proportional advance in increase or
decrease of numbers; continued proportion, arithmetical,
geometrical, or harmonic.
[1913 Webster]
4. (Mus.) A regular succession of tones or chords; the
movement of the parts in harmony; the order of the
modulations in a piece from key to key.
[1913 Webster]
Arithmetical progression, a progression in which the terms
increase or decrease by equal differences, as the numbers
[lbrace2]2, 4, 6, 8, 1010, 8, 6, 4, 2[rbrace2] by the
difference 2.
[1913 Webster]
Geometrical progression, a progression in which the terms
increase or decrease by equal ratios, as the numbers
[lbrace2]2, 4, 8, 16, 32, 6464, 32, 16, 8, 4, 2[rbrace2]
by a continual multiplication or division by 2.
[1913 Webster]
Harmonic progression, a progression in which the terms are
the reciprocals of quantities in arithmetical progression,
as 1/2, 1/4, 1/6, 1/8, 1/10.
[1913 Webster]
