Find the question mark ? figure from answer figure.

From first figure to second the design rotates 90° clockwise.

The corresponding figure of A, introduced as many elements head as the number of side (inside).

(4) the completes figure rotates 180 degree the arc gets laterally inverted and the line segment rotates 90 clock wise .

Answer B

The line segment close to the inner elements moves to the adjacent side in an anti clock wise, the outer element is lost and the remaining figure rotates 90 degree ACW.

From first figure to second figure to the left of sign (::), one side is added to both the geometrical figures.

From first figure to second figure to the left of sign (::), the triangle is converted into square, i.e., one side is added to each design and a circle is introduced inside the concentric squares touching the sides.

From first figure to second figure the two triangles move one step anticlockwise and rotates 45° anticlockwise. The design inside the circle is inverted and the circle becomes elliptical.

The movement of designs from first figure to second figure can be shown as :

From first figure to second figure the main design rotates through 45° clockwise and each line segment is doubled.
