AngleTrigonometryGeometric Construction
This example illustrates the concepts of angles of elevation and depression, involving trigonometry and geometric construction. By constructing angles and segments, students can intuitively understand the definitions of angles of elevation and depression and their applications in real-world problems. It uses Segment, Angle, and other GeoGebra commands. Suitable for middle school and above students.

GeoGebra Commands & Parameters

  1. Segment(G, H) → c
  2. Segment(G, J) → d
  3. Angle(J, G, H) → elevation
  4. Angle(H, G, J) → depression
  5. Segment(H, J) → h
  6. Segment(H, I) → i
  7. Angle(I, H, G) → γ
  8. Angle(G, H, I) → δ
  9. Segment(G_1, J_1) → d_1

AI Drawing Prompt Reference

Draw a triangle with points G, H, and J. Draw a segment from H to J, then draw another segment from G to J, forming two angles, one for elevation and one for depression. Next, draw a segment from H to I to form another angle. Finally, draw a segment from G_1 to J_1 to represent another side of a triangle.
The prompt above was compiled from the original drawing commands and is for reference only.
