Rotation Sequence
Rotation Sequence problems involve shapes that rotate by a fixed angle at each step (e.g., 90° clockwise, 45° anticlockwise). You must determine the rotation rule and find the orientation of the next figure in the sequence.

Introduction to Rotation Sequence
Rotation Sequence problems involve shapes that rotate by a fixed angle at each step (e.g., 90° clockwise, 45° anticlockwise). You must determine the rotation rule and find the orientation of the next figure in the sequence.
Prerequisites
How to Solve Rotation Sequence Problems
Step 1: Observe the orientation of the shape in each figure
Step 2: Determine the angle and direction of rotation between consecutive figures
Step 3: Verify the rotation is constant throughout the sequence
Step 4: Apply the same rotation to the last figure to get the next orientation
Step 5: Consider wrap-around: after 360°, orientation returns to starting point
Step 6: Visualize or sketch the rotated shape if needed
Step 7: Answer with the correct orientation or next figure
Example Problem
Example: Triangle rotates: 0°, 90°, 180°, 270°, ___. Find the next rotation angle. Solution: Step 1: Angles: 0°, 90°, 180°, 270° Step 2: Rotation step = +90° each time Step 3: Next angle = 270° + 90° = 360° (or 0°) Answer: 0° (original orientation)
Pro Tips & Tricks
- Use a reference point on the shape to track rotation
- Common rotation steps: 45°, 90°, 180°
- Clockwise = positive rotation, Anticlockwise = negative rotation
- 90° clockwise = 270° anticlockwise
- 180° rotation flips the shape upside down
- After 4 steps of 90°, the shape returns to original orientation (full cycle)
