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 .

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 .

[

1913 Webster ]

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 :

[

1913 Webster ]

a :

b ::

c :

d ,

or a :

b =

c :

d ,

or a /

b =

c /

d .

[

1913 Webster ]

(

in arithmetic ,

{

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 :

8 :

{

In proportion },

they are morally and politically false ." --
