The two recognized types of "arch" fingerprints are plain arches and tented arches.

Plain arches are characterized by a smooth and continuous flow of ridges that enter from one side, rise in the center, and exit on the opposite side without any significant upward thrust. Tented arches, on the other hand, also have ridges that flow from side to side, but they feature a central core that has a noticeable upward thrust, creating a tent-like appearance.

Understanding these distinctions is crucial for fingerprint analysis, as they help in the classification and identification of individuals based on their fingerprint patterns. Recognizing the difference between these two types of arches allows forensic experts and investigators to accurately interpret fingerprint evidence in various contexts, such as criminal investigations or identification procedures.
