About

Quadrillages

This application helps users explore axial and central symmetry through interactive drawing on a grid. It covers Euclidean geometry concepts like points, lines, and angles, and can even be used for fraction initiation by dividing figures.

Highlights
  • Axial and central symmetry exercises
  • Free drawing for Euclidean geometry
  • Point, line, and figure drawing
  • Angle and area calculations
  • Fraction initiation through division

Placing a point on a grid, drawing lines, drawing figures as proposed by this application can appear as simple and easy. This is not the case and this application that makes it possible to work on the problems of axial and central symmetry is very rich. The "Free Drawing" part full of possibilities practically covers the field of Euclidean geometry: point, line, flat geometric figures, areas, mediator, diagonal, angles etc. Everything seems feasible and the initiation to fractions is even possible which makes it possible to divide a given line or figure into equal parts.
