## Step 1<br />The first question asks about the definition of a fingerprint card and what information it contains. A fingerprint card is a piece of card a series of raised dots that represent a person's fingerprints. The information on a fingerprint card includes the person's name, date of birth, date of submission, and the card's unique identifier.<br /><br />## Step 2<br />The second question asks for the three main patterns found in fingerprints and to describe each type. The three main patterns are arches, loops, and whorls. Arches are characterized by ridges that flow across the finger, loops have ridges that enter on one side and flow out the other, and whorls have circular or spiral patterns.<br /><br />## Step 3<br />The third question asks for a personal definition of fingerprints and how many points need to be identified to confirm a match. Fingerprints are the unique patterns of ridges, furrows, and patterns found on the tips of a person's fingers. To confirm a match, at least 12 points of comparison are needed.<br /><br />## Step 4<br />The fourth question asks what evidence fingerprints are. Fingerprints are evidence because they are unique to each individual and can be left at a crime scene, providing valuable information for criminal investigations.<br /><br />## Step 5<br />The fifth question asks to distinguish between patent, plastic, and latent fingerprints. Patent fingerprints are visible prints left by blood, dirt, or ink. Plastic fingerprints are impressions left in soft materials like wax or paint. Latent fingerprints are invisible prints left by natural oils and sweat on the skin.<br /><br />## Step 6<br />The sixth question asks for the difference between a delta and an arch. A delta is a pattern in fingerprints that resembles a triangle, while an arch is a pattern where the ridges enter on one side and exit on the other side, without any recurving.<br /><br />## Step 7<br />The seventh question asks for the difference between a plain arch and a tented arch. A plain arch is a pattern where the ridges enter on one side and exit on the other side, without any recurving. A tented arch is a pattern where the ridges enter on one side and exit on the other side, but with a recurve that looks like a tent.
