Introduction to Alternating Plus-Circle
Alternating Plus-Circle problems feature a complex alternating pattern between two different composite figures: typically a plus symbol inside a circle, and a rotated square. The pattern may also involve rotation of the square element.
Prerequisites
How to Solve Alternating Plus-Circle Problems
Step 1: Identify the two types of figures in the alternating pattern
Step 2: Type A: plus inside circle (usually constant orientation)
Step 3: Type B: rotated square (rotation may increase each time)
Step 4: Determine the pattern period (usually 2)
Step 5: Identify which type comes next based on position parity
Step 6: If type B rotates, apply rotation pattern to determine orientation
Step 7: Select the figure with correct type and orientation
Example Problem
Example: Plus-in-circle, rotated square, plus-in-circle, rotated square (45°), plus-in-circle, rotated square (90°), ___. What comes next? Solution: Step 1: Pattern alternates between plus-in-circle and rotated square Step 2: Last figure = rotated square at 90° Step 3: Next figure = plus-in-circle Answer: Plus inside circle
