This example demonstrates how to calculate the area and perimeter of a randomly generated triangle. The core mathematical concepts involved include area, perimeter, and geometric construction. Using GeoGebra commands such as Polygon, Line, OrthogonalLine, Intersect, Segment, and Textfield, the triangle can be drawn and its area and perimeter calculated. Suitable for middle school and above students for learning and practicing geometric calculations.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Line(A, B) → d
  3. OrthogonalLine(C, d) → e
  4. Intersect(e, d) → D
  5. Segment(C, D) → f
  6. Textfield(GetArea) → InputBox1
  7. Textfield(GetPerimeter) → InputBox2
