Forensics: Fingerprint Identification Practice

Front

What is a Delta in fingerprint analysis?

Back

A Delta is a triangular area found in fingerprint patterns, where ridges diverge. It is a key feature used in fingerprint identification.

Front

What is a Core in fingerprint analysis?

Back

The Core is the central part of a fingerprint pattern, often where the ridges swirl around.

Front

What is a Ridge Ending?

Back

A Ridge Ending is a type of minutiae where a ridge terminates abruptly.

Front

What is a Short Ridge?

Back

A Short Ridge is a small ridge that does not connect to other ridges, often appearing as a small segment.

Front

What is an Enclosure (eye) in fingerprint analysis?

Back

An Enclosure, also known as an eye, is a type of minutiae where a ridge creates a closed loop.

Front

What is a Spur in fingerprint analysis?

Back

A Spur is a type of minutiae that resembles a small branch off a ridge.

Front

What are the types of whorls in fingerprint patterns?

Back

The types of whorls include Plain, Central Pocket, Double Loop, and Accidental.

Front

What is a Tented Arch?

Back

A Tented Arch is a fingerprint pattern that has a central core and rises sharply, resembling a tent.

Front

What is a Loop in fingerprint analysis?

Back

A Loop is a fingerprint pattern that flows in one direction and returns in the opposite direction, with one delta.

Front

What is a Whorl in fingerprint analysis?

Back

A Whorl is a fingerprint pattern characterized by circular or spiral ridges, with at least two deltas.
