Fingerprints

Front

What is a fingerprint?

Back

A fingerprint is an impression of the pattern of ridges and valleys on the surface of a fingertip.

Front

What are the three main categories of fingerprints?

Back

The three main categories are loops, whorls, and arches.

Front

Define 'loop' in the context of fingerprints.

Back

A loop is a fingerprint pattern that has one or more ridges entering from one side, curving around, and exiting from the same side.

Front

Define 'whorl' in the context of fingerprints.

Back

A whorl is a fingerprint pattern that has at least two deltas and a core, with ridges that form circular or spiral patterns.

Front

Define 'arch' in the context of fingerprints.

Back

An arch is a fingerprint pattern where ridges enter from one side and exit from the other side, with no deltas.

Front

What is a delta in fingerprint analysis?

Back

A delta is a triangular area found in some fingerprint patterns, where ridge lines diverge.

Front

What is a core in fingerprint analysis?

Back

A core is the central part of a fingerprint pattern, often found in whorls.

Front

What is an ending ridge in fingerprint analysis?

Back

An ending ridge is a ridge that terminates or ends abruptly.

Front

What is a bifurcation in fingerprint analysis?

Back

A bifurcation is a point where a single ridge splits into two separate ridges.

Front

How can you identify a loop fingerprint?

Back

A loop fingerprint can be identified by its characteristic ridge pattern that flows in one direction and returns.
