PolygonAngleCoordinate GeometryGeometric Construction
This interactive GeoGebra example explores the properties of a parallelogram. It covers core geometry concepts such as parallel sides, equal opposite sides, and diagonal bisection. Construction relies on commands like Line, Segment, Intersect, and Polygon to define vertices A, B, C, D and shape poly1. Ideal for secondary school students to visualize quadrilateral theorems and geometric relationships dynamically.

GeoGebra Commands & Parameters

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