Let’s discuss the question: how is the area of convergence determined. We summarize all relevant answers in section Q&A of website Achievetampabay.org in category: Blog Finance. See more related questions in the comments below.
How is area of convergence determined quizlet?
Area on Convergence is determined by drawing a straight line through the center of several drops. The place where these lines intersect is the area where the person was standing. Area of Origin is where the wound produced blood.
How do you find the area of the origin of blood spatter?
By measuring the width and length of a single drop of blood, you can determine the angle of impact. By using the Law of Tangents, you can calculate the height from which the blood fell, or the point of origin for the blood.

What is the area of convergence and how does it help an investigator?
Area of convergence- The area on a two-dimensional plan where lines traced through the long axis of several individual bloodstains meet; this approximates the two-dimensional place from which the bloodstains were projected.
What is the pattern of arterial spurting?
Arterial Spurting (or gushing) Pattern — Bloodstain pattern(s) resulting from blood exiting the body under pressure from a breached artery. Back Spatter — Blood directed back towards the source of energy or force that caused the spatter. Bloodstain — Evidence that liquid blood has come into contact with a surface.
What is the area convergence?
Area of Convergence – The area containing the intersections generated by lines drawn through the long axes of individual stains that indicates in two dimensions the location of the blood source.
What software programs are used to determine area of origin?
HemoSpat bloodstain pattern analysis software is used to calculate the area of origin for impact patterns at crime scenes.
How do you draw a line of convergence?
By drawing straight lines down the long axis of the blood spatter and noting the where the lines intersect, this will indicate the line of convergence. To determine where the source of the blood originated, draw a small circle around all the intersecting lines.
What is meant by stain directionality and how is it determined?
What is meant by stain directionality, and how is it determined? An examination of the individual spatter stains within any pattern wil likely establish the direciton the droplets were traveling at the moment they struck the surface.

What does an analyst have to measure to determine the angle of blood spatter?
Using elastic string, the analyst draws lines from each spatter through the level line. Then, he or she uses a protractor on the level line in the area where the strings converge to determine the angle of flight for each spatter.
How can the direction of blood travel be determined?
Analysts can tell the direction of the impacting object by the shape of the spatter (tails point in the direction of motion). Counting the arcs can also show the minimum number of blows delivered. Arterial spray – refers to the spurt of blood released when a major artery is severed.
What can blood spatter analysis determine?
Information that may be gained with bloodstain pattern analysis include, for example, the position of the individual when the blood was deposited (sitting, standing, etc.), the relative position of individuals at the time of bloodshed, the possible type of weapon used as well as possible mechanisms that could have …
What indicates the presence of a specific protein discovered while studying rhesus monkeys?
What is the Rh (Rhesus) factor? A certain blood protein was discovered while studying Rhesus monkeys. The presence of the protein, or lack of it, is known as the Rh factor.
What are the 6 patterns of blood spatter?
There are seven bloodstain categories: (1) passive bloodstain; (2) projected bloodstains; (3) impact spatter; (4) cast-off bloodstains; (5) arterial gush or spurt bloodstains; (6) wipe bloodstain patterns; and (7) transfer bloodstains.
What does area of origin tell investigators?
Area of Origin -‐ The three-‐dimensional location from which blood spatter originated. Backspatter Pattern -‐ A bloodstain pattern resulting from blood drops that traveled in the opposite direction of the external force applied; associated with an entrance wound created by a projectile.

How does one calculate the angle of impact?
The minor axis is the shortest length, or width, of the ellipse. Calculate the angle of impact with the following equation: “i = asin (w/l).” Replace “w” with the length of the minor axis and “l” with the length of the major axis. “Asin” is the arcsin or inverse sine function and is available on most calculators.
What is a parent drop of blood?
parent drop. the droplet from which satellite spatter originated. satellite spatter. small drops of blood that break off from the parent spatter when the parent droplet strikes a target surface. blood spatter.
