Heat, fuel, and oxygen.
A triangle has three components - three sides, three angles, and three vertices. The sides are the line segments that connect the vertices, the angles are the measurements between these sides, and the vertices are the points where the sides intersect.
The triangle of fire is a graphical representation of the three elements needed for a fire: heat, fuel, and oxygen.See the related links, below,for an illustrated explanation of the fire triangle.The fire triangle is made up of oxygen, fuel and heat.
oxygen...fuel...heat (IN THE SHAPE OF A TRIANGLE)
HEAT Heat, the first side of the fire triangle, can come from many sources. It can be generated by sparks from welding operations, discarded cigarette butts, electrical shorts, frayed wiring, friction from power tools, and hot exhaust pipes. FUEL Fuel, the second side of the fire triangle, may be liquid, such as gasoline or solvents; a solid, such as paper or wood scraps; or a gas, such as propane. AIR Air, the third side of the fire triangle, contains oxygen which is necessary to sustain a fire. This is one side of the triangle we can't do much about. Air is usually present.Heat, fuel, and air must be in the proper proportion for fire to occur. It is possible to have these three ingredients without causing a fire. For example, there may not be enough heat or air to ignite the fuel and cause it to burn.
oxygen heat fuel
There is what is known as a "fire/combustion" triangle, which has the three components necessary for fire: oxygen, fuel, heat
The fire triangle is now mostly disused, but it consisted of 3 sides, heat, fuel and oxygen.It was discarded for the "Fire Tetrahedron" which adds in an ignition source.
oxygen, fuel and heat. a fire needs all 3 to survive or it will go out.
All 3 things around the triangle you need to create and sustain fire - heat-fuel-oxygen. If you take any of them out you can not produce or sustain a fire.
Heat, fuel, and oxygen.
The "fire triangle" (or fire tetrahedron) refers to the components of any fire, namely: fuel, heat and oxygen. Forests provide fuel, normal air has plenty of oxygen, and heat can come from lightning or from human carelessness, resulting in forest fires. Under the theory of fire components, if you remove one or more components, the fire will stop. In forest fires you can remove the fuel by "separating" it with a fireline, you can remove the heat by using water or fire retardant. When the wind blows, it adds fresh air (more oxygen) and stimulates the fire's intensity and adds to the convective spread of the fire embers.
The fire triangle consists of three components - Heat, Oxygen and Fuel. All three MUST exist together for a source of ignition to start a fire, which in effect is a chemical reaction. If you remove one of these elements, then the reaction can not occur and hence, no fire.
A triangle has three components - three sides, three angles, and three vertices. The sides are the line segments that connect the vertices, the angles are the measurements between these sides, and the vertices are the points where the sides intersect.

The term "fire triangle", or combustion triangle, refers to the inherent principles in the methodology of making a fire. The "fire triangle" is a model for understanding the resources and methods needed to make a fire.
