What are the 3 types of fingerprint patterns?

Friction ridge patterns are grouped into three distinct types—loops, whorls, and arches—each with unique variations, depending on the shape and relationship of the ridges: Loops – prints that recurve back on themselves to form a loop shape.

What are the 4 different types of fingerprints?

Henry’s four types of pattern groupings (arch, loop, whorl, composite) and their interpretations are as follows:

• Arch. In arches, the ridges of the finger run continuous from one side of the finger to the other with no recurving.
• Loop. In loops, the ridges make a backward turn but do not twist.
• Whorls.
• Composites.

What is arch fingerprint?

Arch fingerprints have ridges that form a hill. Some arches look like they have a pointed tent shape. Arches are the least common type of fingerprint.

What is a loop fingerprint pattern?

A loop is that type of fingerprint pattern in which one or more of the ridges enter on either side of the impression, recurve, touch or pass an imaginary line drawn from the delta to the core, and terminate or tend to terminate on or toward the same side of the impression from whence such ridge or ridges entered.

What are the 7 basic fingerprint patterns?

What are the 7 basic fingerprints patterns?

• Arches. These occur in about 5% of the encountered fingerprints.
• Loops. These can be seen in almost 60 to 70% of the fingerprints that are encountered.
• Whorls.
• Plain arch.
• Tented arch.
• Radial loops.
• Ulnar loops.
• Double loop.
