Geometry Basic Terms 3: Midpoint, Perpendicular, and Segment Verification

①This example demonstrates how to understand basic geometric terms such as midpoint, perpendicular line, and segment by moving points and verifying their characteristics in GeoGebra. ②Core math concepts include the midpoint of a segment, perpendicularity, and dynamic verification of geometric properties (e.g., midpoint bisects the segment, perpendicular line forms a right angle). ③Construction highlights: from the summary, it uses commands Line, OrthogonalLine, Segment, and Midpoint, creating objects A, B, C, D, E, lines a, b, c, and text texto2; users can drag points to observe changes and verify properties. ④Suitable for middle school geometry introduction or self-study, reinforcing basic terminology and dynamic geometry thinking, also useful as an interactive classroom demonstration.
