Types of Patterns and Their Interpretation
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 | II. LOOP | III. WHORL |
| a. Plain arch. | a. Radial loop. | a. Plain whorl. |
| b. Tented arch. | b. Ulnar loop. | b. Central pocket loop. |
| c. Double loop. | ||
| d. Accidental whorl. |
Illustrations 1 to 10 are examples of the various types of fingerprint patterns.
