Basic Geometric Construction: Circles, Lines, and Perpendicular Intersections

This example demonstrates fundamental plane geometry construction techniques using core GeoGebra commands including Circle, Line, Point, OrthogonalLine, Intersect, and Segment. It constructs a geometric figure involving circles, lines, perpendicular lines, and their intersection points. Through key points A, B, C, P, M, L, N and multiple interacting lines and segments, it illustrates positional re
