Over the weekend, I went to my favorite restaurant in Santa Cruz called Tramonti's. I ordered my favorite pizza with ham, mushrooms, and a huge egg on top, and I couldn't resist making a collage of it to show geometric similarities! On the far right of the picture, I have half of the pizza, or a semi-circle equaling 180 degrees. I showed the Arc Addition Postulate because arc ADB plus arc BED is equal to the total of arc ABC. In the top left hand corner of the picture, I proved Theorem 9-3. I showed that the minor arcs FG and HG were congruent because their central angles were congruent. I also was able to prove Theorem 9-5 in the same picture. Diameter FH is perpendicular to chord JK so it bisected the chord and its arc. In the bottom left hand corner, I am just showing that the pizza slice made an isosceles triangle with MN congruent to OM. This pizza was not only delicious, it was full of geometry! (~MG1)
