1. If it is an IQ test, there are two methods.

(1) Play the Rubik's Cube more often to cultivate a three-dimensional sense, which is convenient for converting two-dimensional graphics into three-dimensional. The purpose of the topic itself is to test whether you can directly see the three-dimensional situation after the two-dimensional plane is folded. In fact, it is to examine your three-dimensional memory ability! Pay attention to the stereoscopic memory ability! The key point of transformation is not to get the orientation and angle of the figure wrong.

(2) This kind of problem has skills. Draw a three-dimensional cube on a piece of white paper, then draw six squares and point the arrows at each face of the cube, and then draw a pattern corresponding to each face in each square by rotating the two-dimensional plane (one face at a time, only one face) (you can choose one face as the standard face according to the answer under the topic, such as the face facing you), so that you can find that some faces in the answer are wrong by exclusion, and you can do this.

2. If you mean the junior high school geometry problem (what are you talking about, Tz-||| | | ...)

(1) When drawing, connect each vertex of the graph with a rotation point, and then write down the length of each line segment separately. According to the rotation direction (clockwise or counterclockwise) and angle (how many degrees of rotation), mark the other point (non-rotation point) of each line segment around the rotation point as the point where the original vertex of the original graph should be after rotation, and then connect each newly marked point, which is the rotated graph.

(2) Prove the problem, calculate the problem, etc. Because the solution of the problem itself is only the formula and theorem you have learned, then think about the conditions of the formula and theorem. Rotation itself corresponds to the angular length, so it may constitute congruence, and the new angle generated after rotation may constitute an isosceles triangle, so it may constitute an equal side, so it may constitute a similar triangles or congruence, so that the situation of the other side or the situation of another angle can be deduced (in fact, it is better to use the method of double-sided clamping. For example, if the title asks you to prove something, then you can infer that if you want to prove this, what kind of conditions will you get, and then you can find this condition, and even use theorems and formulas as auxiliary lines, and then write the process according to the original title. )
