1. Write an essay describing the culture and history of the Pythagorean Greeks. Include at least three mathematical developments for which the Pythagoreans are responsible. Dates, places and other cultural information will add to your grade. Continue your essay on the back of this sheet if necessary.
2. You constructed the unique point at which the three angle bisectors of a triangle intersect for homework. This point is the center of the inscribed circle of the triangle. Give a good argument, using perpendicular distances from the angle bisectors to the sides of the triangle, that this must be the case, that your picture was not a lucky inaccuracy.
