Respuesta :
A loop must have one or more ridges entering from one side of the print, recurving, and exiting from the same side.
One or more ridges must enter from one side of the print, recur, and exit from that same side in order for there to be a loop. An ulnar loop is one that faces the little finger and opens in that direction. All loops must contain one delta, which is the ridge point at or immediately in front of the place where two ridge lines (type lines) diverge. If the loop opens toward the thumb, it is referred to as a radial loop.
One or more ridges must enter from one side of the print, recur, and exit from that same side to qualify as a loop.
An ulnar loop is one that opens toward the little finger. A radial loop is one that faces the thumb when it opens. Two diverging ridges, referred to as type lines, encircle the pattern region of the loop. The delta is the ridge point at or closest to the place where two type lines divide. There must be one delta in each loop. The core of the loop pattern is about where it begins and ends.
