Rotation

Elements rotate around a fixed point by a constant angle each step. The most common single rule in EPSO abstract reasoning.

Understanding this pattern

Rotation patterns involve one or more elements turning clockwise or anti-clockwise by a fixed number of degrees between each frame. An arrow might rotate 90° per step, or a dot might orbit around the perimeter of a square. The key is measuring the angle between two consecutive positions and verifying it stays constant. About 40% of EPSO abstract reasoning questions involve at least one rotation.

Example Question 1

Rotation q03_perimeter_dot
Options A B C D E
Correct answer: E

Pattern Rule

The filled dot advances one position clockwise around eight equally spaced points on the square perimeter in every panel. Continue from the fifth position by one more step on the same loop.

Explanation

Option E is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

Example Question 2

Rotation q03_perimeter_dot
Options A B C D E
Correct answer: D

Pattern Rule

The filled dot advances one position clockwise around eight equally spaced points on the square perimeter in every panel. Continue from the fifth position by one more step on the same loop.

Explanation

Option D is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

Example Question 3

Rotation q03_perimeter_dot
Options A B C D E
Correct answer: E

Pattern Rule

The filled dot advances one position clockwise around eight equally spaced points on the square perimeter in every panel. Continue from the fifth position by one more step on the same loop.

Explanation

Option E is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

Example Question 4

Rotation q03_perimeter_dot
Options A B C D E
Correct answer: D

Pattern Rule

The filled dot advances one position clockwise around eight equally spaced points on the square perimeter in every panel. Continue from the fifth position by one more step on the same loop.

Explanation

Option D is the only choice that applies this rule to the next panel. Every other choice stops, reverses, skips, or misaligns at least one part of the pattern.

How to spot it

  • An element appears in different orientations across frames
  • A dot or marker moves to adjacent positions around a shape boundary
  • The overall shape stays the same but its angle changes systematically

Common traps

  • Confusing clockwise and anti-clockwise rotation — check frames 1→2 vs 2→3
  • Assuming 90° when the actual step is 45° or 60°
  • Missing that two elements rotate at different speeds (see: dual-speed)
