This example demonstrates the calculation of perimeter and area for isosceles triangles, including the construction of the incircle. Key math concepts involve perimeter, area, isosceles triangles, incircle, arithmetic, and binomial distribution. GeoGebra commands and objects used include Point, OrthogonalLine, Intersect, Polygon, Perimeter, and PointIn. Suitable for middle school students and above for learning geometric calculations and constructions, as well as basic probability applications.
