In collections Geometry Review
This example demonstrates identifying sides of a right triangle with respect to acute angles. Key mathematical concepts include trigonometric functions (sine and cosine) and geometric construction. Using GeoGebra commands such as RandomElement, Segment, and Sequence, it dynamically illustrates the relationship between sides and angles in a right triangle. Suitable for middle school and above students learning trigonometry and geometric construction.

GeoGebra Commands & Parameters

  1. RandomElement(L) → a
  2. Segment(A_1, B) → g
  3. Sequence(i, i, 3, a - 1, 1) → ML, {3, 4, 5, 6, 7}
  4. Sequence(i, i, a + 1, 10, 1) → MR, {9, 10}
  5. Union(ML, MR) → M
  6. RandomElement(M) → b
  7. Polygon(A_1, B, A) → t1, c, a_1, b_1
  8. Segment(A_1, A) → f
  9. Segment(A, B) → h
  10. Random(1, 5) → n
  11. Angle(B, A_1, A) → α
  12. Textfield(d) → InputBox1
