Thinking in (Semi-)Circles: The Area of the Arbelos Thinking in (Semi-)Circles: The Area of the Arbelos I had trouble finding a good variable for this project, i thought that i could test if the area of the circle from point C to point D on different sized Arbelos. I wanted to prove that the area of the circle is the same area as the Arbelos. I didnt know how to change the sizes of the Arbelos. If you have any ideas for a different way of experimenting with Arbelos, or how to help me with how Read more

Science Fair Project Idea
thumbnail Here is a challenging problem for anyone with an interest in geometry. This project requires background research to solve it, but it is an excellent illustration of visual thinking in mathematics. Figure 1 below shows a series of circles (iC₁, iC₂, iC₃, ..., iC₃₀), inscribed inside an arbelos. What is an arbelos? The arbelos is the white region in the figure, bounded by three semicircles. The diameters of the three semicircles are all on the same line segment, AC,… Read more

Science Fair Project Idea
thumbnail This a straightforward, but interesting, project in geometry. It is a good first proof to try on your own. You should be able to figure it out by yourself, and you'll gain insight into a basic property of circles. Figure 1 below shows a semicircle (AE, in red) with a series of smaller semicircles (AB, BC, CD, DE, in blue) constructed inside it. As you can see, the sum of the diameters of the four smaller semicircles is equal to the diameter of the large semicircle. The area of the larger… Read more
