Construct Perpendicular Bisector (Midpoint) Demo

This example demonstrates how to construct the perpendicular bisector of a segment and automatically mark its midpoint in GeoGebra. Core mathematical concepts include segments, midpoints, perpendicular bisectors, perpendicularity, and symmetry. Construction steps: create segment AB with the Segment command, then use points A, B and the function f (or related tools) to generate the perpendicular bisector; the software computes the midpoint and draws the perpendicular line. Suitable for middle‑school geometry instruction, high‑school review, and introductory geometric construction activities, serving as classroom interaction or self‑study material.
