Axial Symmetry Course
This course builds mastery in axial symmetry, starting with geometric constructions using compass and straightedge, moving to coordinate-based reflections across axes and lines, and algebraic formulas for any line ax+by+c=0. Learners gain skills for precise calculations, rigorous justifications, and practical classroom teaching with checks for preserved properties like distances and angles, ensuring confident application in maths education and advanced geometry.

What will I learn?
Explore axial symmetry through hands-on compass-and-straightedge constructions, core geometric principles, and properties that remain invariant under reflection. Progress to coordinate methods for reflecting over axes and y=x, general line equations ax+by+c=0, and practical teaching tools including verification activities for classroom use.
