This example demonstrates how to graph horizontal and vertical lines, covering core concepts like linear equations and coordinate geometry. It uses commands such as Line, Point, Angle, and Intersect in GeoGebra. Suitable for middle school and above students learning about linear equations and function graphs.

GeoGebra Commands & Parameters

  1. Line(A, xAxis) → a
  2. Line(A, yAxis) → b
  3. Point(b) → B
  4. Point(a) → C
  5. Angle(B, A, C) → α
  6. Point(b) → D
  7. Intersect(b, xAxis) → E
  8. Intersect(a, yAxis) → F
  9. Intersect(b, a) → J

AI Drawing Prompt Reference

Draw two perpendicular lines, one horizontal and one vertical, and mark their intersection point. Choose an arbitrary point on the horizontal line, draw a line segment from this point to the vertical line, and measure the angle between the line segment and the horizontal line. Then, take another point on the vertical line, connect it to the intersection points of the horizontal and vertical lines, forming two intersecting line segments, and mark their intersection point.
The prompt above was compiled from the original drawing commands and is for reference only.
