Paper Work versus Dynamic Mathematics

IDevice Icon Triangle and Square
  1. On a plane paper, construct
    • a triangle
    • a square
  2. Discuss with a colleague and enumerate, with explanations, a procedure you would prescribe to a novice interested in constructing the two mathematical objectives

iDevice icon Mathematical Properties

What are the mathematical properties of

  • a triangle
  • a square
IDevice Icon Dynamic Geometry
Construct a square on the given GeoGebra workspace. You may open the file "Square_1.html" in case this page does not open


iDevice icon Justification
Use GeoGebra tools and menus to convince your colleague that you have constructed a square
