Dual Pattern: Rotation and Shading
Dual Pattern problems involve two simultaneous transformations: rotation (angle change) and shading (fill intensity change). Each transformation follows its own independent pattern. You must track both and apply both to find the next figure.

Introduction to Dual Pattern: Rotation and Shading
Dual Pattern problems involve two simultaneous transformations: rotation (angle change) and shading (fill intensity change). Each transformation follows its own independent pattern. You must track both and apply both to find the next figure.
Prerequisites
How to Solve Dual Pattern: Rotation and Shading Problems
Step 1: Track rotation angles separately from fill levels
Step 2: Determine the rotation pattern (step angle, direction)
Step 3: Determine the shading pattern (increasing darkness, alternating, etc.)
Step 4: Apply the rotation step to the last figure's angle
Step 5: Apply the shading step to the last figure's fill
Step 6: Combine both transformations to create the next figure
Step 7: Select the figure with correct rotation and shading
Example Problem
Example: Square rotates 45° clockwise and alternates filled/unfilled. Angles: 0°,45°,90°,135°. Fills: filled, empty, filled, empty. Next? Solution: Step 1: Rotation step = 45°, next angle = 180° Step 2: Fill pattern: filled, empty, filled, empty → next = filled Step 3: Next figure: filled square rotated 180° Answer: Filled square at 180°
