这个范例演示了长方体的几何构造。它涉及立体几何中的核心概念，如点、线、面和空间中的几何变换。通过使用GeoGebra命令如Intersect、Point、Segment等，可以动态地展示长方体的各个面和边。适合初中及以上学生或教师用于教学和学习。

GeoGebra 命令及参数

Intersect(xAxis, yAxis) → D
Point(Circle[D, abs(a)]) → C
Segment(D, C) → b
Circle(C, c) → d
OrthogonalLine(C, y = 0) → e
Intersect(d, e, 2) → G
OrthogonalLine(G, e) → f
Intersect(f, yAxis) → H
Polygon(D, C, G, H) → poly1, a_1, b_1, c_1, d_1
Prism(poly1, g) → h, A, edgeAE, edgeBF, edgeCG, edgeDH, edgeEF, edgeFG, edgeGH, edgeEH, B, F, E, faceABFE, faceBCGF, faceCDHG, faceADHE, faceEFGH
Textfield() → inputBox1
Volume(h) → w
Distance(D, C) → distanceAB
Distance(C, G) → distanceBC
Distance(G, F) → distanceCG
