A fingerprint is a unique pattern created by the friction ridges on the fingers. A fingerprint pattern which possesses either an angle, an upthrust, or two of the three basic characteristics of a loop. If n=1, consider the straight line joining the core and the delta.

Any Fingerprint Pattern That Has At Least Two Of The Three Basic Requirements Of A Good Loop Pattern (Sufficient Recurve, Delta, And Ridge Count Across A Looping Ridge) Is Classified As A Tented Arch.
A tented arch is defined by having an upthrust greater than 45 degrees in the middle of the print. Define or describe plastic prints.
