Geometry Vocabulary Demo: Polygon & Line Construction

① This example demonstrates the construction of a polygon, lines, segments, and rays in GeoGebra to illustrate geometric vocabulary terms visually. ② Core mathematical concepts include polygons, lines, segments, rays, point labeling, and text annotations. ③ Construction highlights: Polygon command creates poly1; Line, Segment, and Ray commands generate lines a, b, c, d and rays e, f, g; objects comprise vertices A, B, C, D, E, F, G, H, I, J, L, M, N, O and text1. ④ Suitable for middle‑school geometry basics, high‑school analytic geometry review, and geometric construction practice, serving as classroom demonstration or self‑study material.
