+## Tessellations
 
 A tessellation is a mosaic that is created by repeating a figure to cover the surface without leaving empty spaces or overlapping the figures. A *regular tessellation* is a figure that is made by repeating the same *regular polygon*, like triangles, squares or hexagons. (A regular polygon is a polygon where all sides are congruent and the angles that form the sides are congruent.)

 The `Tessellations.pro` project available in `http://bitbucket.org/eip-uprrp/repetitions1-tessellations` contains the `Tessellation` class, which is an abstraction of a tessellation with squares, and the `DrawingWindow` class. The code shown in Figure 2 creates a `DrawingWindow` called `w`, a `Tesselation` called `t` and places the tessellation in position (50,100). Notice that the `addTessellation` method of the `DrawingWindow` class should be invoked to draw the tessellation.

+2. The `Tessellations.pro` project contains the `Tessellations` and `DrawingWindow` classes and the `foo` function. Configure the project and run the program by clicking the green arrow in the menu on the left side of the Qt Creator window. You should see a window similar to the one in Figure 5.
 
      This figure is created with the `foo` function shown in Figure 4 and explained in Example 1. The `foo` function is invoked from `main()`. In this laboratory experience you will only be making changes to the `main()` function.
 
      Study the `foo` function once again and notice the creation of the objects from the `Tessellations` class, the use of the `setRotation` method, and the `move` method to set the tessellation in the desired position. Notice how the instructions in the `for` loop in the function use the loop's counter to determine the square's position and how the rotation's value is incremented. Also notice that you will need to use the `addTessellation` method to add the tessellation to the `w` window.
