Implemented in:France

Description: The aim is to work on different triangles with the students and to make them discover the relationship between the longest side of the triangle and the other two sides. They find answers to questions such as: “If the angles of the triangle stay the same, can the length of the sides change?” Students have to construct different triangles using spreadsheets to find out what changes if they modify the angle or the length of a side. Furthermore, they learn about Pythagoras’ theorem with the teacher in the role of facilitator.
