Right Prism in GeoGebra: Parametric Construction and Net

This example demonstrates how to construct a right prism in GeoGebra, producing the 3D solid and its corresponding net (unfolding) with clear geometric annotations. The key mathematical ideas are the defining property of a right prism (lateral edges perpendicular to the base), the relationship between base polygons and lateral faces, and how these structures remain consistent under parameter changes. Construction highlights: it uses Prism to create the solid; Point, Polygon, and Segment to build and control the base and boundary edges; Intersect to locate vertices via geometric intersections for correct connectivity between faces; Rotate (and RotateText) to show rotations and maintain readable labels during view/expansion; Midpoint to assist with auxiliary points; Angle and Textfield to annotate angle relationships; and Net to generate the unfolding. The model is further controlled by input boxes (InputBox1/2/3) and parameter-driven objects (e.g., t1/t2, dimensions) for interactive exploration. Suitable for secondary school through early university, especially for solid geometry, geometric construction, and parametric visualization tasks.
