Select a figure from the Answer Set (1, 2, 3, 4, 5) which would continue the series indicated by the four figures of the Problem Set (A, B, C, D).

Clearly, the square moves one step CW each time (each step being equal to half a side of the square). The triangle moves one, two, three, .... steps ACW in subsequent steps. So, in the next fig., the square should come to the lower right position and the triangle should move four steps ACW to come to the lower middle position.

Hence, the answer is (5).
