Front

What are the three main types of fingerprint patterns?

Back

Loop, Arch, Whorl

Front

What is a Loop fingerprint?

Back

A fingerprint pattern that has one or more ridges that enter from one side, curve around, and exit the same side.

Front

What is an Arch fingerprint?

Back

A fingerprint pattern that has ridges that enter from one side and exit the other side, forming a wave-like pattern.

Front

What is a Whorl fingerprint?

Back

A fingerprint pattern that has circular or spiral ridges that form a complete circuit.

Front

How can you identify a Loop fingerprint?

Back

Look for ridges that flow in one direction and then curve back towards the same side.

Front

How can you identify an Arch fingerprint?

Back

Look for ridges that rise in the center and slope downwards on both sides.

Front

How can you identify a Whorl fingerprint?

Back

Look for two or more deltas and a core in the center of the pattern.

Front

What is the significance of fingerprints in forensic science?

Back

Front

What is a delta in fingerprint analysis?

Back

A delta is a triangular area found in some fingerprint patterns, indicating a change in ridge direction.

Front

What is a core in fingerprint analysis?
