Fingerprint Arches: Plain or Fancy?

What are fingerprint arches?

Fingerprint arches can be:

1) plain arches

2) fancy arches

Answer:

Fingerprint arches can be plain or fancy, and they are a shape formed by identical wedge-shaped stones.

Explanation:

Fingerprint arches can be classified as plain arches and fancy arches. The arch itself is a shape that can be formed variously to create different architectural spaces. It consists of identical wedge-shaped stones called voussoirs, with the keystone being the topmost voussoir that holds the arch together. Arches like these can be seen in structures such as aqueducts, vaults, and even in Gothic architecture.

Pointed arches, in particular, are efficient in distributing weight and allow for the construction of thinner walls. Fingerprint patterns vary across the globe, much like skin color, and can be used for identification purposes. They are not markers of race and are difficult to see.
