向量解析几何几何作图
该范例演示了水平线和垂直线的绘制方法。核心数学概念包括直线的性质和坐标几何。通过使用Polygon, Segment, LaTeX, Text等命令，可以构造出水平和垂直线。适合初中及以上学生学习直线的相关知识。

GeoGebra 命令及参数

  1. Polygon({(-11, -11), (-11, 11), (11, 11), (11, -11)}) → viewBox
  2. Segment((-11, horValue), (11, horValue)) → horLine
  3. Segment((verValue, -11), (verValue, 11)) → verLine
  4. LaTeX("\textbf{Question: }What are some properties of horizontal and vertical lines?") → QUESTION
  5. LaTeX("\textbf{Instructions: }Use the sliders on the edges of the grid to move the\\horizontal and vertical lines. What do you notice about the coordinates\\of the indicated points?") → INSTRUCTIONS
  6. Text(hor1, hor1 + offset, true, true) → hor1Label
  7. Text(hor2, hor2 + offset, true, true) → hor2Label
  8. Text(hor3, hor3 + offset, true, true) → hor3Label
  9. Text(ver1, ver1 + offset, true, true) → ver1Label
  10. Text(ver2, ver2 + offset, true, true) → ver2Label
  11. Text(ver3, ver3 + offset, true, true) → ver3Label
