Cosine Ratio Demo

This example illustrates how to construct the cosine ratio in a right triangle. It covers core math concepts like cosine ratio, right triangles, and angle measurement. The construction uses GeoGebra commands such as Line, OrthogonalLine, Point, Polygon, Angle, Perimeter, and PointIn, with objects like A, C, f, g, B, h, t1, a, b, c, γ, perimetert1, Pointt1, α, β, and text elements. It is suitable for middle school and above students learning basic trigonometric functions and geometric constructions.
