Trigonometric Ratios Demo by Andy Greasley

This example demonstrates the calculation and visualization of trigonometric ratios (sine, cosine, tangent) in right triangles. It involves core mathematical concepts such as the definition of trigonometric functions, relationships between side lengths in right triangles, and angle measurement. The construction uses GeoGebra commands like Rotate for rotation, Angle for angle measurement, Line and Segment for drawing, OrthogonalLine for creating perpendicular lines, and Intersect for finding intersection points. Suitable for high school mathematics teaching, helping students intuitively understand the connection between trigonometric functions and geometric properties of triangles.
