👉 In geometry, an isogonal line or isogonal conjugate of a line \(l\) through point \(A\) is another line that passes through the same point but is perpendicular to \(l\). It can be defined as a line that is perpendicular to the given line at its end point. The term "isogonies" refers to these lines and their properties, which are often used in geometry. Isogonal lines are an important concept in Euclidean geometry because they allow for the definition
