Draw another equilateral triangle with three-inch sides from the center section of each side. One triangle will shoot off to the left on the left side, another to the right on the right side, and the other downward from the baseline. The outer perimeter of your triangle will now be the shape of a dodecagon.... Instructions 1 Fold the paper diagonally twice then unfold it, creating an X-shaped crease and four triangles on the paper. 2 Fold the paper in half lengthwise so that you have three folds.

5/12/2011 · for those of you who are interested in a nice way to fold a dodecagon. I learned this method from dasa who learned it from daniel kwan who discovered it because he knows about geometry. a lot. there are instructions somewhere on daniel kwan's photostream, too. I saw them some day but I figured it'd be faster for me to draw this than to how to delete a file in zip Thus, the triangles are formed by drawing the diagonals of the decagon. The general formula for finding the number of triangles that can be formed is "n-2," where “n” is the number of sides of the polygon.. How to draw the phantom

- Archimedes used the idea of inscribing and circumscribing polygons to come up with an estimate for π. An inscribed polygon is a polygon whose vertices are on the edge of a circle. A circumscribed polygon is a polygon whose vertices are outside the edge of a circle and have every edge of the polygon touch the circle exactly once. Archimedes used two ideas to draw regular inscribed and
- ‘Dissections can get quite elaborate: A seven-pointed star becomes two heptagons; a dodecagon turns into three identical squares; and so on.’ ‘If you have a 40 yard loop with a post every yard, it doesn't matter whether it's a circle, a square, or a dodecagon.’

- Number the vertices of the dodecagon from 1 to 12 in cyclic order, then draw the chords joining both 1 and 12 to both 5 and 8. This cuts the dodecagon into six pieces that can be rearranged to …
