Writing Perpendicular Line Equations

This example demonstrates how to construct the equations of perpendicular lines using GeoGebra, involving core math concepts like equations, continuity, logic, line segments, and optimization. Key GeoGebra commands and objects used include Line, OrthogonalLine, Angle, Slope, and FractionText. Suitable for high school students and teachers learning about perpendicular line equations and their constructions.
