5 overlapped triangles arranged to make a pentagon but also a cool pentagram in the middle 5 重叠 三角形 5 重叠的三角形
this is as close as you can get making a pentagon with triangles that don't overlap, that is with them pointing inward towards the center 五角大楼 三角形 几乎五角大楼

4 plain Valknut symbol vector files. 2 unicursal, 2 non-unicursal symbol vector files. The Valknut (Old Norse valr, "slain warriors" + knut, "knot") is a symbol consisting of three interlocked triangles, and appears on various Germanic objects. A number of theories have been proposed for its significance. -Wikipedia These symbol vector files are great for a quick grab for Old Norse/Viking inspired tattoos, jewelry designs, etc. 结 三角形 维京 符号矢量 4 简单 Valknut 外观设计

This picture is meant to show people the supreme shapes. They were designed to be big enough to see clearly. I made them in inkscape, which is currently the best free vector graphics program available for Linux. When dealing with the natural world we live in, we tend to not appreciate the most basic things around us. Many colors, numbers, and shapes, make up the objects which we see and feel. Although there are endless variations of everything,I have noticed that almost everything man made tends to resemble one of 4 common shapes. Also, look up the definition of supreme and you'll see why I like this word. http://en.wiktionary.org/wiki/supreme regular quadrilateral(square) The square is my favorite shape of all. All of it's four sides are the same length. Many people think that a square and rectangle are different things, however, a square is a type of rectangle. Other rectangles may have a different width/height ratio but all types of rectangles are useful for building things(brick houses,legos,chessboards,etc). It's also the only type of shape which can actually be represented accurately on a computer screen because pixels are squares. If you look around you, you'll probably find that squares and other rectangles(all of which can be divided into smaller squares), are the most commonly made shape of all man-made objects. The 3 dimensional version of a square is called a cube. Most furniture and storage containers are a rectangle on every side. regular triangle A triangle is a 3 sided shape. All triangles are interesting, however, the most commonly used triangle is a regular or equilateral triangle. Regular triangles have something in common with squares in that both of them can tesselate. This means that it's possible fit a bunch of them together with no gaps. Many times, the are useful in making other shapes. regular hexagon A hexagon has 6 sides, but a regular hexagon is the most useful because it is the regular polygon with the most sides that can still tesselate perfectly! A regular hexagon can be formed with 6 regular triangles. circle circles are totally different from the other 3 supreme shapes. They do not tesselate, they can't be described by a number of sides. However, there are two reason that I include them in my definition of supreme shapes. First, they occur in God's creation more than anything else. Almost all plants have circular parts. The stems of plants(and trunks of trees), many fruits, and maybe every living animal. Although not all things are perfect circles, many things on the human body are mostly round. Rarely do you find anything that is flat or straight. The second reason is that they are useful for anything that is designed to move. Think of wheels on everything or spheres which are used for nearly every sport. Round things move easy. This is the total opposite of rectangles which are useful when you need something to stay in one place. 广场 圆 三角形 最高的形状
I like tessellations of all types. Usually I do regular triangles but right triangles are cool too. 权。三角形。tesselation 直角三角形 Tesselation 45
this shows how right triangles can tessellate in ways that resemble a regular triangle tessellation. There are 4 possibilities so I did them all in subsquares. 权利 三角形 直角三角形 Tesselation 组合
I am very proud of this picture. For so long I've been trying to find a way to fit regular triangles into a square. I found that it works if I rotate the triangles just right. I also added the red green and blue triangles just to fill the extra space. 广场 满足 三角形 广场满足三角形

I put my favorite regular polygons inside circles and gave them colors to match the circle opposite them. Each type of polygon appears 3 times. I also have a black circle in the middle because I don't want black to be forgotten. 中圈彩虹 4 多边形 三角形 广场 中圈彩虹 4 多边形
