Line test - graphic reasoning -7- different graphic classes

When the similarity between graphics is not high, it is classified as the problem of different graphics .

For dissimilar graphics , The following aspects are mainly investigated ：

 

Catalog

One 、 Image characteristics

1. symmetry

2. Straightness

3. Closed and open

Two 、 Quantitative relation

1. Number of enclosed areas

2. Number of parts

3. Number of lines

4. Number of intersections

3、 ... and 、 Element distribution

---

Although the figures are not similar , But when each image is distinctive , First consider the characteristics of the image ：

One 、 Image characteristics

1. symmetry

（1）

 2,5,6 Is a symmetrical figure ,1,3,4 It is a centrosymmetric figure .

（2）

The axis of symmetry rotates clockwise 45 degree . choose A.

（3）

 

Add the number of symmetry axes in turn 1, choose A.

（3）

 

All figures are centrosymmetric , choose C. 

2. Straightness

（1）

  The figure is the alternation of outer curve and inner straight and outer straight inner curve in turn , So choose C.

（2）

Longitudinal law finding , The first column is curve graph , The second column is a straight line graph , The third column is a combination of straight and curved figures . choose D. 

3. Closed and open

（1）

3,4,6 There are no closed areas ;1,2,5 There are enclosed areas . 

（2）

Odd position figures are closed figures , Even position graphics are open graphics . choose D. 

Two 、 Quantitative relation

1. Number of enclosed areas

（1）

The number of enclosed areas of all figures is 6, So choose A. 

2. Number of parts

（1）

The first line is a part , The second line has two parts , The third line is all three parts . choose D.

（2）

  The graph has three parts , So choose C.

3. Number of lines

（1）

 

  Add the number of curves from left to right in turn 1, choose B.

4. Number of intersections

（1）

  Add points from left to right in turn 1, choose B.

3、 ... and 、 Element distribution

1. The relative position

（1）

“ Japan ” Rotate clockwise in turn , So choose A.
