AngleTrigonometryGeometric Construction
This example demonstrates the definition and calculation of trigonometric functions. It involves core math concepts like trigonometric ratios, angles, and right triangles. Construction highlights the use of GeoGebra commands such as Ray, Point, Segment, OrthogonalLine, Polygon, and Angle. Ideal for high school mathematics teaching and geometric construction learning.

GeoGebra Commands & Parameters

  1. Ray(B, B_1) → a_1
  2. Point(a_1) → A
  3. Segment(A, B) → c
  4. OrthogonalLine(B, c) → c_2
  5. Point(c_2) → D
  6. Ray(B, D) → d
  7. Point(d) → C
  8. Polygon(C, A, B) → poly1, b, e, a
  9. Angle(B, A, C) → α
  10. Angle(A, C, B) → β
  11. Angle(C, B, A) → γ

AI Drawing Prompt Reference

Draw a right triangle ABC with point B as the right angle vertex. First, draw a ray from point B to point B1, then take point A on this ray. Next, draw a segment AB. From point B, draw an orthogonal ray to segment AB and take point D on this ray. Then, draw a ray BD and take point C on this ray. Finally, draw triangle ABC and label angles A, B, and C.
