What is the common visual representation of an inverted cone pattern?

The common visual representation of an inverted cone pattern is accurately depicted as a two-dimensional triangle shape. This triangular representation effectively illustrates how the inverted cone narrows at the top and widens at the base. In practical fire investigation contexts, an inverted cone pattern helps to depict the area of origin of a fire, where the flames and heat rise and subsequently, the smoke and heat spread outward in a conical shape.

When analyzing fire scenes, understanding this pattern is crucial as it assists investigators in determining the fire's point of origin by considering the way the fire and smoke interact with the surrounding environment. This shapes the approach taken to locate potential sources of ignition and evidence in fire investigations.
