This example demonstrates how to construct a rectangle using GeoGebra. Key mathematical concepts include geometric construction and linear equations. By using commands such as Line, OrthogonalLine, Point, Intersect, and Polygon, the vertices of the rectangle can be constructed. Suitable for students at the junior high school level and above to learn geometric construction and the application of linear equations.

GeoGebra Commands & Parameters

  1. Line(A, B) → f
  2. OrthogonalLine(B, f) → g
  3. Point(g) → C
  4. OrthogonalLine(C, g) → h
  5. OrthogonalLine(A, f) → i
  6. Intersect(h, i) → D
  7. Polygon(A, B, C, D) → q1, a, b, c, d

AI Drawing Prompt Reference

Draw a rectangle by first setting two diagonal points A and B on the coordinate plane, then draw a line g perpendicular to AB through point B, which intersects at point C. Next, draw a line h perpendicular to g through point C, and draw a line i perpendicular to AB through point A. The intersection of lines h and i gives point D, the other diagonal point of the rectangle. Finally, connect points A, B, C, and D to form the rectangle.
