Tenprint Fingerprint Certification Tenprint Fingerprint Identification Techniques 2

Question 1

Which ridge detail is defined as a short ridge that does not connect to another ridge at either end?

Accepted Answer

Short ridge (independent ridge)

Answer

A short ridge, also called an independent ridge, is a ridge segment that terminates at both ends without connecting to other ridges.

Question 2

When comparing latent prints to tenprint exemplars, which method involves superimposing one image over another at the same scale?

Accepted Answer

Overlay comparison

Answer

Overlay comparison involves placing one image directly over another at the same magnification to visually align corresponding ridge details.

Question 3

In the Henry Classification System, a finger is assigned a value only if it bears which pattern type?

Accepted Answer

Whorl

Answer

In the Henry system, numerical values are assigned exclusively to fingers bearing whorl patterns; loops and arches receive no numerical value.

Question 4

What term describes the imaginary line drawn between the two type lines at the point where they diverge in a loop pattern?

Accepted Answer

Delta line

Answer

The delta line is the imaginary line connecting the two diverging type lines and is used to locate the delta point in a loop.

Question 5

Which of the following conditions would most likely cause a fingerprint to be classified as 'scarred' rather than assigned a pattern type?

Accepted Answer

A permanent scar that obliterates ridge flow

Answer

Permanent scarring that destroys the ridge pattern prevents reliable classification and is notated as a scar rather than a pattern type.
