Fingerprint Identification Knowledge Quiz

1. What type of primary patter of fingerprints is represented here?

Loop

Whorl

Arch

Accidental

The type of primary pattern of fingerprints represented here is an arch.

Explanation

The type of primary pattern of fingerprints represented here is an arch.

2. What type of primary pattern is represented here? What pattern is represented here?

Loop

Whorl

Arch

Accidental

The primary pattern represented here is a whorl. A whorl pattern is characterized by ridges that form a circular or spiral shape, with two deltas (triangular-shaped areas) located on either side of the pattern. This type of pattern is less common compared to loops and arches, and is typically found on the fingertips. Whorls can be further classified as plain whorls, central pocket loops, double loop whorls, and accidental whorls.

4. What type of primary pattern of fingerprints is represented here? What is the pattern?

Loop

Whorl

Arch

Accidental

Loops will start and end on the same side. Arches will go from one side of the finger to the other. Whorls will have a 360 degree.

Explanation

5. What secondary characteristic (found in loops and whorls) is presented here?

Fork

Whorl

Bridge

Delta

A delta is a secondary characteristic found in loops and whorls. It is a triangular shaped pattern that appears when a ridge splits into two ridges and then comes back together to form one ridge. This pattern resembles the Greek letter delta (∆), which is why it is called a delta.

6. What type of secondary pattern is indicated by the arrow?

Fork

Eye/Enclosure

Island

Bridge

Eye: An empty "pocket" caused by two ridge lines meeting and separating -forming an empty area.

7. What secondary pattern is indicated by the arrow?

Core

Bridge

Crossover
