1. Lines or curves that make equal angles with a given set of lines or curves; in geometry, lines that intersect a family of curves at a constant angle.
Usage: technical; mathematics; plural form
2. In triangle geometry, points or lines related to isogonal conjugates, where two points are isogonal conjugates if their corresponding cevians are reflections of each other across the angle bisectors.
Usage: technical; geometry; plural form

Examples

• The isogonals of a family of circles can be computed using differential geometry.
• In triangle geometry, the orthocenter and circumcenter are isogonal conjugates.
• The study of isogonals helps mathematicians understand the properties of curves and their intersections.
• Isogonals are important in advanced geometry and have applications in physics and engineering.
