Line test - graphic reasoning - 6 - similar graphic classes

In general , When the constituent elements of a group of graphics are the same or the similarity of graphics is very high , Call such a figure a similar figure .

Similar figures mainly investigate the following laws ：

 

Catalog

One 、 translation

Two 、 rotate

3、 ... and 、 Go to different places and keep the same

Four 、 Go and save the difference

5、 ... and 、 superposition  

---

One 、 translation

1.

By observing the first group of figures , The figure gradually converges to the middle , So choose A.

 2.

  The translation law of the circle is to walk one grid to the right and then two grids to the left ; Black fast translation rule is the opposite . choose D.

Two 、 rotate

1.

  Look at the first and second lines , The law is counterclockwise rotation 90 degree , So choose C.

3、 ... and 、 Go to different places and keep the same

1.

Observe the first set of figures , The rule is that the third picture is the second picture, which turns up and down, and then goes to the same place as the first picture .

choose D.

 2.

  Look at each line to see , The rule is to keep the same part of the first and second pictures for the third picture , Remove the different parts . So choose D.

Four 、 Go and save the difference

1.

The rule is to remove the same part of the first two pictures and then superimpose , choose A.

 2.

  choose B.

5、 ... and 、 superposition  

Stacking includes regular stacking and direct stacking .

1.

This topic is called rule superposition . Look at the first and third lines , The law is ： white + black = white ; black + white = black ; white + white = black ; black + black = white . So choose A.

 2.

This topic is called column rule , The last two pictures in each column are directly superimposed to form the third picture . So choose D.

 3.

This topic is called rule superposition , From the first group of figures , Law as point + spot = white ; white + white = white ; spot + white = spot ; white + spot = spot .

choose B.

 4.

  This topic is called rule superposition , It can be seen from the first group that it is left oblique + Tilt left = white ; Right oblique + Tilt left = black ; white + white = white ; Right oblique + white = Right oblique .

choose B.
