In collections Parallel Lines Cut by a Transversal
This example illustrates the properties of alternate exterior angles. Alternate exterior angles are formed when a transversal intersects two parallel lines. The example uses GeoGebra commands such as point, line, intersection, and angle measurement to demonstrate these relationships. Suitable for middle school and above students to learn about geometric transformations and angle relationships.

GeoGebra Commands & Parameters

  1. Line(A, B) → f
  2. Line(C, f) → g
  3. Line(D, E) → h
  4. Point(f) → F
  5. Intersect(f, h) → G
  6. Point(h) → H
  7. Angle(H, G, F) → α
  8. Angle(h, g) → β
