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.
Many food items are wrapped in filo pastry, either in bite-size triangles or in large sheets: kotopita (chicken pie), spanakopita (spinach and cheese pie), hortopita (greens pie), kimadopita (ground meat pie) also known as kreatopita (meat pie), kolokythopita (zucchini pie), and others. They have countless variations of pitas (savory pies).
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.
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.
A polyiamond (also polyamond or simply iamond, or sometimes triangular polyomino [1]) is a polyform whose base form is an equilateral triangle.The word polyiamond is a back-formation from diamond, because this word is often used to describe the shape of a pair of equilateral triangles placed base to base, and the initial 'di-' looks like a Greek prefix meaning 'two-' (though diamond actually ...
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).
To determine the length of this side, the two right triangles DCM and QCM are depicted below the circle. Using Pythagoras' theorem and two sides, the hypotenuse of the larger triangle is found as /. Side h of the smaller triangle then is found using the half-angle formula:
