See the individual, find symmetry, fold the overlap along the axis, and rotate the center as well.
If there is no symmetry, if you want to close it, don't forget to form an angle and count the closed surfaces.
If it is not closed, it must be opened. Whether it is on or off, it is the same law of finding numbers.
With straight, * * * bend, straight bend apart, see two lines alternating.
A sum, also common, will repel each other, and the path will not be repeated.
The same group of drawings, multi-faceted, ask what are the characteristics and options to judge.

Graphic reasoning should pay attention to the following skills:
First, establish the concept of "element". Think of each figure as an inseparable "element". And careful observation, good at refining. Elements generally include points, lines, faces and bodies. Judging from the real questions in the past two years, the main investigation is "body", that is, small graphics make up large graphics. Whether the number of each element changes, whether the rotation or rotation direction is regular, whether the graphics overlap each other and whether the shapes are equal. So be careful when choosing the answer, and don't make visual mistakes. You should also learn to use mutated thinking. For example, sometimes an element is missing, but it can be said that there are laws of "being" and "not being".
Second, look for the law of change. The law of its change can be seen from many angles. Compared with many previous series types and calculation methods, the law of graphic change is more complicated and may be an unheard of "law", which depends on the logical thinking ability and flexibility of candidates to deal with and solve.
Third, special rules should be adopted for special graphics. For example, the law of element combination reasoning of element combination graphics. If there are four "circles", it can only be regarded as "circles" without counting the number of "circles", that is to say, it has great interference to the problem that the local content of a graphic "constitutes an element".
