What is the term for the two distinct ridge formations within the double loop fingerprint pattern?

The term that refers to the two distinct ridge formations within the double loop fingerprint pattern is "deltas." In a double loop pattern, you can observe two separate loop formations that create a distinctive feature recognizable by ridge characteristics. These ridge formations converge and diverge in such a way that they produce two triangular points known as deltas. Deltas are crucial in fingerprint analysis as they help forensic experts classify and differentiate between fingerprint patterns.

The other options do not specifically relate to the feature described. Whorls are a different type of fingerprint pattern characterized by a circular or spiral arrangement of ridges, while arches have ridges that enter one side and exit the other without any deltas. Loops refer to a pattern that has one delta and one core but does not capture the concept of the two distinct formations found in double loops.
