Last crawled date: 5 years, 10 months ago
A tactile geometric proof for the area of a circle. Print 12 copies of the circle segment, sitting vertically for the best Braille.
You can arrange them in a circle and in an approximate parallelogram to show that the area of a circle is pirr. This is a common proof in early high school mathematics. This tactile version allows blind or low vision students to access the concept themselves.
