Description: 
  • Ensino Médio::Matemática
  • Let P be a point connected to and inside the vertices of a 2n-gon. Number the triangles counterclockwise from 1 to 2n. Then the sum of the areas of the even-numbered triangles is equal to the sum of the areas of the odd-numbered triangles. Drag the point P to change the figure
