AngleFunctionTrigonometry
This example demonstrates the trigonometric relationships in a right triangle. Key mathematical concepts include sine, cosine, and tangent. Using GeoGebra commands such as Segment, OrthogonalLine, and Point, the example dynamically shows how the values of trigonometric functions change with the angle. Suitable for middle school and above students to learn the basic properties of trigonometric functions.

AI Drawing Prompt Reference

Draw a right triangle ABC with A as the right angle. From point B, draw a perpendicular line to AC, intersecting at point D. From point C, draw a perpendicular line to BD, intersecting at point E. Label ∠BAC as α, ∠ABC as β, and ∠BCA as γ. Then, from point A, draw a perpendicular line to BC, intersecting at point F. From point B, draw a perpendicular line to AF, intersecting at point G. Label ∠BAF as θ, ∠ABF as η, and ∠BFA as ι. Finally, from point C, draw a perpendicular line to AB, intersecting at point H. Label ∠CAH as ε, ∠ACH as ζ, and ∠HAC as δ.
