2017年1月3日 · Taken from Wikipedia and Mathwords, the following are the definitions of Shape and Figure: From Wikipedia. A geometric shape is the geometric information which remains when location, scale, orientation and reflection are removed from the description of a geometric object. From Mathwords. A geometric figure is any set of points on a plane or in ...
Are triangles the strongest shape? - Mathematics Stack Exchange
2015年8月12日 · If the links are rigid (i.e. can't be deformed) then there will be no relative motion between any two pin-jointed links of a triangle while quadrilateral & other polygons have degree of freedom $\ge 1$ hence other polygons can be made to out of shape by applying force so triangles are only rigid or the strongest shapes.
geometry - What is the name of this geometric shape?
2015年5月23日 · $\begingroup$ I don't believe there's an official name for this shape, so the trick is to find a concise descriptor. "Concave bisymmetric hexagon" would (I think) cover #1, but there's no elegant counterpart for #2.
The shape of Pringles potato chip - Mathematics Stack Exchange
The reason for it might be something like this- Anything when given heat tries to minimize its surface energy. e.g. Bubble are formed because of surface tension force, to minimize stresses on surface of bubble, it forms spherical form, hence only stress acting on it will be normal pressure (Actually it is more precise to say static pressure).

2017年4月2日 · There's a couple different ways. Each equation can be considered a two dimensional plane in three dimensional space. The solutions $(x,y,z)$ to the equation are the points of th
Software for drawing geometry diagrams - Mathematics Stack …
2010年8月10日 · Desmos Graphing Calculator, is, yes a graphing calculator, but it is also really useful for geometric drawing. On their homepage they illustrate several examples of how versatile the tool is for drawing. The main drawback of the program is that you need to know the algebraic (Cartesian, Parametric, or Polar) equations behind your shape to draw it.

Is there a name for a 2-dimensional dumbbell like shape?
2017年4月13日 · Is there a mathematical name for a 2-dimensional shape in the general form of a dumbbell? That is two circular nodes connected by a center beam such as shown in this image from this answer. It could also be thought of as a circle that has been pinched together.
Is it possible to draw this picture without lifting the pen?
2015年12月31日 · In mathematics, drawing a geometric shape without lifting the pen and without tracing the same line more than once is identical to finding a Eulerian trail in the undirected graph composed by the intersections of the shape.
