Students explore trigonometric functions and ratios using this interactive simulation tool. Learners manipulate angles within right triangles to observe how sine, cosine, and tangent ratios change, building conceptual understanding of trigonometry. Supports TEKS G.9.A, G.9.B, and Pre-Calculus P.4.E (trigonometric ratios).
Skills: trigonometric ratios, right triangle relationships, angle measurement, mathematical exploration. Grades 10-12.
