Rotation Pattern
Rotation Pattern problems involve figures that rotate by a fixed angle (usually 90°, 180°, or 270°) at each step. You must identify the rotation direction and magnitude to determine the next or missing figure in the sequence. These problems test your mental rotation ability and understanding of angular transformations.

Introduction to Rotation Pattern
Rotation Pattern problems involve figures that rotate by a fixed angle (usually 90°, 180°, or 270°) at each step. You must identify the rotation direction and magnitude to determine the next or missing figure in the sequence. These problems test your mental rotation ability and understanding of angular transformations.
Prerequisites
How to Solve Rotation Pattern Problems
Step 1: Identify a reference point on the first figure (e.g., a vertex, a marked side, or a distinct feature)
Step 2: Compare the first and second figures to determine the rotation angle and direction
Step 3: Verify that the same rotation applies between the second and third figures
Step 4: Apply the rotation rule to the last given figure to find the next figure
Step 5: If a figure is missing in the middle, work backward using opposite rotation
Step 6: For 180° rotation, the figure will be upside down
Step 7: Select the option that matches the rotated figure
Example Problem
Example: Figures: Triangle pointing up, Triangle pointing right, Triangle pointing down, Triangle pointing left, ___ Find the next figure. Solution: Step 1: Figure1: ▲ (pointing up) Step 2: Figure2: ► (pointing right) → 90° clockwise rotation Step 3: Figure3: ▼ (pointing down) → another 90° clockwise rotation Step 4: Figure4: ◄ (pointing left) → another 90° clockwise rotation Step 5: Next: 90° clockwise from left → pointing up (▲) Answer: Triangle pointing up (▲)
Pro Tips & Tricks
- Clockwise (CW): right turn, Anticlockwise (ACW): left turn
- 90° CW: up → right → down → left → up (cycle of 4)
- 90° ACW: up → left → down → right → up (cycle of 4)
- 180° rotation: up → down, right → left (cycle of 2)
- For figures with asymmetric features, track the position of a specific element (e.g., a dot, a line, a colored section)
- If rotation is not consistent, check if the pattern alternates direction
