VectorCoordinate GeometryGeometric Construction
This example demonstrates the construction of horizontal and vertical lines. Key mathematical concepts include the properties of straight lines and coordinate geometry. Using commands like Polygon, Segment, LaTeX, and Text, horizontal and vertical lines can be constructed. Suitable for students in middle school and above to learn about straight lines.

GeoGebra Commands & Parameters

  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
