Monday, Dec. 20 boys were at the fifth taken with the evidence of the play Christmas and colleague asked me to repeat the songs. There was still a quarter of an hour, they were tired of singing. In a flash I got the idea to create a work Christmas: the star. Is that all? Exclaimed Nicholas, the usual polemical! Ok, but you will do this is a star with the points exactly the same. Construct a regular pentagon with a protractor: Do not forget the rule! And the star has to do with the Pentagon? Nicola always! You do it and then you'll see. By the way, how the revenues will top 5? Nicola peeps the simple rules that I write the last time and exclaims: 360:5! Okay, do the division and draw your Pentagon.
When all have designed the pentagon, I ask you to draw the star in it. The boys are puzzled. Somebody tries to do it with the ruler, but he sees that it is not perfect. Invitation to then draw all the diagonals of the polygon e. ......... wow, how nice! At the center of another pentagon is upside down! Then draw another star, say proud to have them amazed. Time's up: a house, delete all lines that do not serve colored and the two stars with the same color but different shades.
