This example demonstrates the relationship between the area and perimeter of a triangle. Key mathematical concepts include the area and perimeter of a triangle. Using GeoGebra commands such as Line, Polygon, Intersect, etc., a dynamic triangle can be constructed to observe changes in its area and perimeter. Suitable for middle school and above students to learn geometry and algebra.

GeoGebra Commands & Parameters

  1. Line(A, B) → f
  2. Polygon(A, C, B) → t1, b, a, c
  3. OrthogonalLine(C, c) → g
  4. Intersect(f, g) → D
  5. Segment(D, C) → h

AI Drawing Prompt Reference

Draw a triangle ABC, then draw the perpendicular bisector of side AB, which intersects AB at point D. Draw line segment CD. Observe how the area and perimeter of triangle ABC change.
