Geometric \Ge'o*met"ric\, Geometrical \Ge'o*met"ric*al\, adjective [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.

Syn: geometric. [WordNet 1.5]

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.

{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} (Zool.), 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.

Proportion \Pro*por"tion\, noun [F., fr. L. proportio; pro before + portio part or share. See {Portion}.]

1. The relation or adaptation of one portion to another, or to the whole, as respect magnitude, quantity, or degree; comparative relation; ratio; as, the proportion of the parts of a building, or of the body.

Formed in the best proportions of her sex. --Sir W. Scott.

2. Harmonic relation between parts, or between different things of the same kind; symmetrical arrangement or adjustment; symmetry; as, to be out of proportion. "Let us prophesy according to the proportion of faith." --Rom. xii. 6.

3. The portion one receives when a whole is distributed by a rule or principle; equal or proper share; lot.

Let the women . . . do the same things in their proportions and capacities. --Jer. Taylor.

4. A part considered comparatively; a share.

5. (Math.) (a) The equality or similarity of ratios, especially of geometrical ratios; or a relation among quantities such that the quotient of the first divided by the second is equal to that of the third divided by the fourth; -- called also {geometrical proportion}, in distinction from arithmetical proportion, or that in which the difference of the first and second is equal to the difference of the third and fourth.

Note: Proportion in the mathematical sense differs from ratio. Ratio is the relation of two quantities of the same kind, as the ratio of 5 to 10, or the ratio of 8 to 16. Proportion is the sameness or likeness of two such relations. Thus, 5 to 10 as 8 to 16; that is, 5 bears the same relation to 10 as 8 does to 16. Hence, such numbers are said to be in proportion. Proportion is expressed by symbols thus: a:b::c:d, or a:b = c:d, or a/b = c/d. (b) The rule of three, in arithmetic, in which the three given terms, together with the one sought, are proportional.

{Harmonical proportion} or {Musical proportion}, a relation of three or four quantities, such that the first is to the last as the difference between the first two is to the difference between the last two; thus, 2, 3, 6, are in harmonical proportion; for 2 is to 6 as 1 to 3. Thus, 24, 16, 12, 9, are harmonical, for 24:9::8:3.

{In proportion}, according as; to the degree that. "In proportion as they are metaphysically true, they are morally and politically false." --Burke.

Proportion \Pro*por"tion\, verb (used with an object) [imp. & p. p. {Proportioned}; p. pr. & vb. n. {Proportioning}.] [Cf. F. proportionner. Cf. {Proportionate}, v.]

1. To adjust in a suitable proportion, as one thing or one part to another; as, to proportion the size of a building to its height; to proportion our expenditures to our income.

In the loss of an object we do not proportion our grief to the real value . . . but to the value our fancies set upon it. --Addison.

2. To form with symmetry or suitableness, as the parts of the body.

3. To divide into equal or just shares; to apportion.

From WordNet (r) 3.0 (2006) [wn]:

noun

1: the quotient obtained when the magnitude of a part is divided by the magnitude of the whole

2: magnitude or extent; "a building of vast proportions" [syn: {proportion}, {dimension}]

3: balance among the parts of something [syn: {symmetry}, {proportion}] [ant: {disproportion}]

4: the relation between things (or parts of things) with respect to their comparative quantity, magnitude, or degree; "an inordinate proportion of the book is given over to quotations"; "a dry martini has a large proportion of gin" [syn: {proportion}, {ratio}]

5: harmonious arrangement or relation of parts or elements within a whole (as in a design); "in all perfectly beautiful objects there is found the opposition of one part to another and a reciprocal balance"- John Ruskin [syn: {proportion}, {proportionality}, {balance}]
