If we label the four elements in the figure as ; then the arrow at position 1-rotates 45 ^oACW and 135 ^oACW alternately; the element at position 2 rotates 90 ^oACW and moves to position 3 in each step; the element at position 3 rotates 90 ^oACW and moves to position 4 in each step and the element at position 4 moves to position 2 and gets replaced by a new element in each step.

In each step, the upper element is lost; the middle element reduces in size and becomes the upper element; the lower element enlarges and becomes the middle element and a new element appears at the lower position.

One of the designs (with white triangle at the centre) moves CW while the other design (with black triangle at the centre) moves ACW.

The V sign moves two spaces (each space is equal to half-a-side of the square boundary) and one space ACW alternately. The '=' sign moves one space and two spaces ACW alternately.

In each step, both the elements move one space (each space is equal to half-a-side of the square boundary) downwards. Once any of the two elements reaches the lowermost position, then in the next step, it reaches the uppermost position in the next column to the right.

In one step, one half-leaf is lost from the CW-end and three half-leaves are added at the ACW-end. In the next step, one half-leaf is lost from the CW-end and two half-leaves are added at the ACW-end.

One circle is replaced by a new symbol in each step and this replacement takes place on either ends alternately. The complete figure rotates 45 ^oACW in each step.

Only in fig. (4), the black triangle and the black circle lie at the two ends of the same diameter.

All other figures can be rotated into each other.

In each one of the figurers except fig. (3), the number of half-leaves is one more than the number of line segments.
