In collections Introduction to Angles
This example demonstrates the properties of vertical angles formed by intersecting lines. It involves core math concepts like angles, intersecting lines, perpendicularity, and angle measurement. Construction highlights include using Line, Intersect, and Angle commands in GeoGebra. Suitable for middle school mathematics instruction to visually illustrate the congruence of vertical angles.

GeoGebra Commands & Parameters

  1. Line(A, B) → a
  2. Line(C, D) → b
  3. Intersect(a, b) → E
  4. Angle(D, E, A) → α
  5. Angle(A, E, C) → β
  6. Angle(C, E, B) → γ
  7. Angle(B, E, D) → δ
