This example demonstrates how to calculate the distance between two points in a Cartesian coordinate system. It involves core mathematical concepts from coordinate geometry, specifically the distance formula. The construction utilizes GeoGebra commands and objects such as Segment, Line, Intersect, Angle, and Midpoint. It is suitable for middle school students and above to learn and understand basic coordinate geometry calculations, as well as for high school mathematics teaching demonstrations.

GeoGebra Commands & Parameters

  1. Segment(A, B) → a
  2. Line(B, yAxis) → b
  3. Line(A, xAxis) → c
  4. Intersect(b, c) → C
  5. Segment(A, C) → d
  6. Segment(C, B) → e
  7. Angle(B, C, A) → α
  8. Midpoint(d) → D
  9. Midpoint(e) → E
