What geometric shape is typically associated with a "V" pattern in fire investigation?

In fire investigation, a "V" pattern is typically associated with the movement and spread of fire, particularly in the context of analyzing burn patterns on surfaces. This shape arises from the way fire travels and the heat it generates, causing damage in a specific fashion as it moves upward and outward from its ignition point.

The "V" pattern is indicative of the fire's point of origin, where the most intense heat and damage occur at the apex of the "V". As the flames spread outwards, they create a wider area of damage that tapers down, forming the characteristic shape. Investigators use this pattern to help determine the direction of fire spread and may provide insights into how and possibly why the fire started in a certain area.

Understanding this pattern is crucial for accurately identifying the source of the fire, which is key in any fire investigation process. The other shapes do not correspond to the unique characteristics of fire behavior and are therefore not applicable in this context.
