2) Turn clockwise. The first picture is circle 1, square 2, solid 3 and triangle 4.

The second picture, triangle 1, circle 2, square 3, solid 4,

So the third picture is in the order of top left and bottom right, solid 1, triangle 2, circle 3 and square 4.

So the fourth picture is in the order of upper left and lower right, square 1, solid 2, triangle 3 and circle 4 (the fourth picture given in the question is wrong)

3) Because the middle circle is symmetrical, the triangle above is drawn.
