TriangleAngleTrigonometry
This applet demonstrates the relationship between angles and side lengths in right triangles, helping to understand the connection between angles and side lengths. Key concepts include trigonometric functions and side length ratios. It uses commands such as Point, Polygon, Dilate, and Angle in GeoGebra. Suitable for middle school and above students learning trigonometry and geometric construction.

GeoGebra Commands & Parameters

  1. Point(xAxis) → B
  2. Polygon(A, B, C) → poly1, c, a_1, b
  3. Dilate(A, a, A) → A'
  4. Dilate(B, a, A) → B'
  5. Dilate(C, a, A) → C'
  6. Polygon(A', B', C') → poly1', adjacent, opposite, hypotenuse
  7. Angle(B', A', C') → β
