This example demonstrates how to construct a right triangle using GeoGebra and explore its related properties. The core mathematical concepts involved include trigonometry, similarity transformation, and coordinate geometry. Construction highlights involve using commands like Segment, Point, Rotate, Angle, Line, and Intersect; suitable for high school mathematics teaching and geometric construction learning.

GeoGebra Commands & Parameters

  2. Point(a) → A
  3. Segment((0, 0), A) → adj
  4. Rotate(B, (-α), A) → B'
  5. Angle(B', A, B) → β
  6. Line(A, B') → c
  7. Intersect(c, yAxis) → C
  8. Segment(C, B) → opp
  9. Segment(C, A) → e
  10. Angle(B, C, A) → γ
  11. Angle(A, B, C) → δ
