PolygonAngleTrigonometryGeometric Construction
This applet demonstrates a parallelogram to help students discover its unique properties. Key mathematical concepts include angles and trigonometry. It is constructed using GeoGebra commands such as Segment, Line, Intersect, and Polygon. Suitable for middle school and above students learning geometric construction.

GeoGebra Commands & Parameters

  1. Segment(A, B) → a
  2. Segment(A, D) → b
  3. Line(D, a) → c
  4. Line(B, b) → d
  5. Intersect(c, d) → C
  6. Segment(D, C) → e
  7. Segment(B, C) → f
  8. Polygon(A, B, C, D) → poly1, a_1, b_1, c_1, d_1
