Answer 1

whorls

Step-by-step explanation:

Whorls. Whorls represent 34 percent of all fingerprint patterns. At least one ridge in a plain whorl pattern makes a complete circuit in the form of a circle, oval or spiral, and there must be at least two triangular shapes called deltas. ... Central pocket loop whorls make a complete circle inside the two deltas.
