This example demonstrates how to find the circumcenter of a triangle by constructing the perpendicular bisectors of its sides. Key mathematical concepts include the definition and properties of the circumcenter. It uses GeoGebra commands such as Polygon, LineBisector, and Intersect. Suitable for middle school and above students learning triangle geometry.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → t1, c, a, b
  2. LineBisector(C, B) → f
  3. LineBisector(B, A) → g
  4. Intersect(f, g) → D
