This example demonstrates how to calculate the area of a triangle using geometric construction. Key mathematical concepts include the properties of triangles and coordinate geometry. Using GeoGebra commands such as Polygon and Distance, the lengths of the sides and the area of the triangle can be dynamically displayed. Suitable for students in middle school and above to learn methods of calculating the area of a triangle.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → t1, c, a, b
  2. OrthogonalLine(A, a) → f
  3. Intersect(f, a) → D
  4. Distance(A, D) → distanceAD
  5. Distance(C, B) → distanceCB
  6. Line(C, B) → g
  7. OrthogonalLine(A, g) → h
  8. Intersect(g, h) → E
  9. Segment(A, E) → i
