Types Of Patterns



Fingerprints may be resolved into three large general groups of

patterns, each group bearing the same general characteristics or

family resemblance. The patterns may be further divided into

sub-groups by means of the smaller differences existing between the

patterns in the same general group. These divisions are as follows:



I. ARCH



a. Plain arch.

b. Tented arch.



II. LOOP



a. Radial loop.

b. Ulnar loop.



III. WHORL



a. Plain whorl.

b. Central pocket loop.

c. Double loop.

d. Accidental whorl.



Illustrations 1 to 10 are examples of the various types of fingerprint

patterns.
