Area and Perimeter Calculation

This example demonstrates how to calculate the area and perimeter of polygons using GeoGebra. Core math concepts include area, perimeter, upper and lower sums or Riemann sums, linear functions, symmetry, and incircle. Construction highlights involve using commands like Intersect for intersection points, OrthogonalLine for perpendicular lines, and Polygon for polygon creation, with parameters a, b, c, d. Suitable for middle school and above, focusing on geometric computation and concept understanding.
