**Matrix explanation - Static patterns**

The previous patterns are all based on a change. Change of location, number, angle or other properties of the figures (such as color, dotted, etc.). However, in some problems with matrices, a static pattern also applies. Examples of static patterns are:

- All rows contain 2 black squares and 4 gray circles (which can be divided completely differently over the different squares of the row).
- All figures combined per column have 15 corners.
- Each row contains two figures that make an angle of 45 degrees and 3 figures that make an angle of 90 degrees.
- etc.

It is often useful to see if similarities can be found between all rows and / or all columns. The most obvious similarities are easy to find.
