Each module joins others at the vertices of a polyhedron to form a polygonal face. The tabs form angles on opposite sides of an edge. For example, a subassembly of three triangle corners forms a triangle, the most stable configuration. As the internal angle increases for squares, pentagons and so forth, the stability decreases.
Unfold these two radial folds. Make another fold across the top connecting the ends of the creases to create a triangle of creases. Unfold this fold as well. Fold one layer of the open point upward and flatten it using the existing creases. A petal fold is equivalent to two side-by-side rabbit ears, which are connected along the reference crease.
There is a "fasting" (νηστίσιμη; "nistisimi"), or vegan, version of spanakopita, eaten during Lent and other religious fasts. This version has spinach, onions or green onions, other green herbs like dill, parsley, or celery as filling and uses olive oil and a little wheat flour but no eggs or dairy products.
The fold-and-cut problem asks what shapes can be obtained by folding a piece of paper flat, and making a single straight complete cut. The solution, known as the fold-and-cut theorem, states that any shape with straight sides can be obtained. A practical problem is how to fold a map so that it may be manipulated with minimal effort or movements.
For strips too short to apply this method directly, one can first "accordion fold" the strip in its wide direction back and forth using an even number of folds. With two folds, for example, a 1 × 1 {\displaystyle 1\times 1} strip would become a 1 × 1 3 {\displaystyle 1\times {\tfrac {1}{3}}} folded strip whose cross section is in the shape of ...
The napkin folding problem is a problem in geometry and the mathematics of paper folding that explores whether folding a square or a rectangular napkin can increase its perimeter.
Delta Delta Delta was founded by Sarah Ida Shaw, Eleanor Dorcas Pond, Florence Isabelle Stewart, and Isabel Morgan Breed at Boston University. [2] Three women's fraternities were already represented at Boston University (Kappa Kappa Gamma, Gamma Phi Beta, and Alpha Phi).
Interlaced triquetra which is a trefoil knot. The triquetra (/ t r aɪ ˈ k w ɛ t r ə / try-KWEH-truh; from the Latin adjective triquetrus "three-cornered") is a triangular figure composed of three interlaced arcs, or (equivalently) three overlapping vesicae piscis lens shapes.
