👉 The term "isogonic" refers to a graph that has one line of symmetry, which means it can be folded along any point and still look the same. This property allows for many mathematical operations such as addition, subtraction, multiplication, division, and exponentiation, which are all possible on graphs with one line of symmetry. Isogonic graphs are often used in geometry to represent shapes that have two or more dimensions and need to be symmetrical with respect to a line. Isogonic
