auxiliary line
An extra line or segment drawn in a figure to help complete a proof
An auxiliary line is a geometric line that is added to a figure or diagram to help in solving a problem or to provide additional information. It is typically not a part of the original figure or diagram and does not change its essential properties.
In geometry, auxiliary lines are often used in proofs to help demonstrate the validity of a theorem or to simplify a complex problem. For example, an auxiliary line can be used to create similar triangles, which can be useful in proving the congruence of two triangles.
In algebra, auxiliary lines are sometimes used to aid in graphing a function or in solving an equation. For instance, a dashed line may be added to a graph to represent an asymptote, which indicates the behavior of the function as it approaches a particular value.
Overall, auxiliary lines are a helpful tool for making complex problems more manageable and for demonstrating the steps of a solution in a clear and logical manner.
