Isosceles Triangle and Derivative Application

This example demonstrates the dynamic relationship between the tangent line at the apex of an isosceles triangle and its base as the apex moves. Core math concepts include isosceles triangle properties, the geometric meaning of derivatives (tangent slope), and analytical geometry construction. GeoGebra commands used are points, lines, polygons, tangents, and sliders. Suitable for high school mathematics teaching to understand the integration of derivatives and geometric figures.
