Front

What is a delta in fingerprint patterns?

Back

A delta is a triangular area found in fingerprint patterns, particularly in loops and whorls, where ridge lines diverge.

Front

What is an eye pattern in fingerprints?

Back

An eye pattern is a secondary fingerprint pattern characterized by a circular or oval shape, resembling an eye.

Front

What is a bridge in fingerprint patterns?

Back

A bridge is a secondary characteristic in fingerprints where two ridges are connected by a short ridge.

Front

What are the primary types of fingerprint patterns?

Back

The primary types of fingerprint patterns are loops, whorls, arches, and accidental patterns.

Front

What defines a loop fingerprint pattern?

Back

A loop fingerprint pattern is characterized by ridges that enter from one side, loop around, and exit the same side.

Front

What defines a whorl fingerprint pattern?

Back

A whorl fingerprint pattern is characterized by circular or spiral ridge patterns that have at least two deltas.

Front

What defines an arch fingerprint pattern?

Back

An arch fingerprint pattern is characterized by ridges that rise in the center, creating a wave-like appearance.

Front

What is an accidental fingerprint pattern?

Back

An accidental fingerprint pattern is a combination of two or more different patterns, making it unique and irregular.

Front

How can you identify a loop fingerprint?

Back

A loop fingerprint can be identified by the presence of one delta and ridges that flow in a circular pattern.

Front

How can you identify a whorl fingerprint?

Back

A whorl fingerprint can be identified by having two or more deltas and a circular or spiral pattern.
