Translation:

You are a development engineer from the ITI1521A consulting box. You are recruited by a civil engineering design office to develop a program that manages regular geometric shapes. They need to calculate the center, perimeter, area and determine the nature of geometric shapes (Rectangle, Square, Isosceles Triangle, Equilateral Triangle, Rectangle Triangle...). In this exercise, we are interested in regular geometric shapes.

The design department developed a class diagram (Figure 1) to represent the inheritance relationships between classes:
