Vector Proofs in Geometry

Vector proofs in geometry is part of the Vectors topic in NSW Year 12 Mathematics Extension 2 (NESA outcome ME2-12-02). This subtopic defines the medians, altitudes, perpendicular bisectors and angle bisectors of a triangle and recognises these definitions in vector form.

Students and teachers will cover how to solve problems and prove geometric results in two and three dimensions using vectors — turning classical geometry into concise vector arguments, a distinctive skill in the HSC Extension 2 course.
