基本形在我们的生活中随处可见，例如：矩形的宣传栏、门窗、各种指示类标志等，造型简单且运用广泛。平面构成中将基本形进行组合即可得到新的图形，例如：把三角形进行简单组合，可让人联想到连绵起伏的山峦；将椭圆形重叠堆积，能让人想起层叠的树叶。
Basic shape can be seen everywhere in our life, such as rectangular billboards, doors and windows, various kinds of signs, etc. In plane composition, new shapes can be obtained by combining the basic shapes. For example, simple combination of triangles can remind people of rolling mountains; overlapping of ellipses can remind people of cascading leaves.

不同的基本形群组能带给人们不同的视觉享受。基本形的组合方式可以在大小、方向、形状、色彩、位置，以及空间等方面进行变化，创造出新的形态。这样的构成简单、容易，有助于各种表现元素的应用和组构画面，进而使设计作品更丰富。
Different basic shape groups can bring people different visual enjoyment. The combination of basic forms can change in size, direction, shape, color, position and space to create new forms. This kind of composition is simple and easy, which is helpful for the application of various performance elements and the composition of the screen, thus making the design works richer.

在不断的实践设计中，人们总结出平面构成的几种方式：包括线性构成、对称或放射形构成、三角形构成以及多方向的自由组合构成。将这些构成方式应用到平面设计中能够更加快捷、明确地完成设计。
In the continuous practice of design, people summed up several ways of plane composition: including linear composition, symmetrical or radial composition, triangle composition and multi-directional free combination. Applying these forms to graphic design can complete the design more quickly and clearly.

在平面构成中，线性构成主要是用线来表现物体的结构形态并将多个艺术形象有机地连接起来，这样有助于增强画面的内在联系，能够保持一致的风格特征，使造型简练且设计独特，给人无限趣味。
In plane composition, linear composition mainly uses lines to express the structural form of objects and organically connect multiple artistic images, which helps to enhance the internal connection of the screen, maintain consistent style features, make the modeling concise and unique, and give people infinite interest.

对称是指在画面中心假定一条中心线(或中心点)，在其左右、上下或周围配置同形、同量、同色的视觉元素，是最经典的构图方式，这样的构图方式能在人的心理上产生平衡、稳重的感觉。
Symmetry means that a central line (or central point) is assumed in the center of a picture, and visual elements of the same shape, quantity and color are arranged on the left, right, up, down or around it. It is the most classic way of composition, which can produce a sense of balance and steadiness in people's psychology.

放射性构成则是将多个元素以某个点作为中心向同一方向由密变疏地变化，呈现放射的状态。两种组合形式在视觉上都给人井然有序的感觉，对称构成显得工整，放射形构成具有动态美。
The radioactive composition is that many elements change from dense to sparse in the same direction with a certain point as the center, showing a radioactive state. The two combination forms give people a sense of order in vision, the symmetrical structure is neat, and the radial structure has dynamic beauty.

三角形构成是一种古老的艺术形式。在人类的远古时期，人们在使用土块、茅草建造房屋时就发现，三角形的房屋不容易积水，而且抗风，比较坚固。正角形能给人留下稳固不易撼动、力量均衡的印象。
Triangle formation is an ancient art form. In ancient times, when people used soil and thatch to build houses, they found that triangular houses were not easy to accumulate water, and they were wind resistant and relatively strong. The positive angle can leave the impression of stability and balance of strength.
