A compass and straight edge.
No single tool will suffice. You will need a pair of compasses and a straight edge.
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.

Learning to use a compass and straightedge is essential because it develops foundational skills in geometry and enhances spatial reasoning. These tools enable precise constructions and problem-solving without the reliance on technology, fostering a deeper understanding of mathematical principles. Additionally, mastering these techniques encourages logical thinking and creativity, which are valuable in various fields beyond mathematics. Lastly, it connects learners to historical practices in geometry, enriching their appreciation of mathematical history and culture.
