No, although it is essential for a fire. In technical terms a fire needs two chemical ingredients: fuel and oxidizer. The fuel is whatever is burning, whether it is wood, gasoline, or methane. Oxygen is the oxidizer.
The three elements of the fire triangle that must be present are Heat, Oxygen, and Fuel. This has recently been changed though from the fire triangle to the fire tetrahedron. This includes Heat, Oxygen, and Fuel as well. But, it also contains a fourth, chemical reaction.
Heat, Fuel, Oxygen and Chemical Chain Reaction
There is what is known as a "fire/combustion" triangle, which has the three components necessary for fire: oxygen, fuel, heat
For fire you need three main ingredients. First you need a fuel, this fuel can be anything that burns like wood for example. Second you need oxygen, without oxygen a fire cannot burn. Finally you need heat, even though fires give off heat you still need it to start a fire. If you remove any one of these three ingredients then the fire will die.
Three things are needed for fire to burn, often referred to as the triangle of fire. Oxygen, heat and fuel, it is only the fuel that burns, the oxygen and heat together cause the fuel to burn.
If you remove fuel, oxygen, or both from a fire, the fire goes out.

Fuel, oxygen and heat or an ignition source are the components needed for a fire.
it is Oxygen, heat, fuel. the fire triangle is just a short saying for all these elements
