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:
a. Plain arch.
b. Tented arch.
a. Radial loop.
b. Ulnar loop.
a. Plain whorl.
b. Central pocket loop.
c. Double loop.
d. Accidental whorl.
