AngleGeometric Construction
This example demonstrates how to construct line segments and angles using GeoGebra. Key mathematical concepts include line segments and angles. Commands used include Segment, Distance, Point, Rotate, and Angle. Suitable for middle school and above students to learn geometric construction.

GeoGebra Commands & Parameters

  1. Segment(A, B) → a
  2. Distance(A, B) → distanceAB
  3. Point(Circle[C, 6.74]) → E
  4. Segment(C, E) → b
  5. Segment(F, G) → c
  6. Segment(G, H) → d
  7. Rotate(H, 45*°, G) → H'
  8. Angle(H, G, H') → α
  9. Rotate(G, 45*°, F) → G'
  10. Angle(G, F, G') → β

AI Drawing Prompt Reference

First, draw a figure that includes line segments and angles. Key objects are line segments a, b, c, d, angles α and β, and rotated points H' and G'. Relationships: line segments a and b may be connected, line segments c and d may be connected, angles α and β may be related. Construction order: first draw line segments a and b, then draw point E, then draw line segment b, then draw line segments c and d, then rotate points H and G, then draw angle α, then rotate point G, then draw angle β.
