Pattern Completion — Questions & Answers
Pattern completion questions show a square pattern with one quarter missing and ask which piece completes it. Most patterns are mirrored across the middle lines or turned like a pinwheel.

How to approach
Check whether the visible quarters mirror each other across the middle lines or turn 90° from one to the next.
Apply the same symmetry to find the missing quarter.
Watch for pieces that are flipped the wrong way or copied without flipping.
5 solved Pattern Completion questions
Which piece completes the pattern? (The missing quarter is marked ?)
Solution — answer C
Each quarter is the mirror image of the quarters beside it, across the middle lines. Mirroring the neighbouring quarters into the top-right corner gives option C.
4 steps · reveal one at a timeStep 1: Find the rule
The pattern describes a relationship between the four quarters of a figure. We need to identify how the quarters relate to each other to find the missing piece.
Step 2: Apply the rule
The rule states that each quarter is the mirror image of the quarters beside it, across the middle lines. This means we should look at the pieces adjacent to the missing quarter.
Step 3: Determine the piece
To complete the pattern, we must mirror the neighbouring quarters into the missing top-right corner. This will give us the correct design for that section.
Step 4: The answer
So the answer is (C) Figure C. Mirroring the neighbouring quarters into the top-right corner, according to the established rule, results in Figure C.
Which piece completes the pattern? (The missing quarter is marked ?)
Solution — answer C
Each quarter is the one before it turned 90° clockwise, like a pinwheel. Turning the quarter before the bottom-left one gives option C.
3 steps · reveal one at a timeStep 1: Find the pattern rule
The problem asks us to complete a pattern. We need to look at the relationship between the existing quarters to find the rule that connects them.
Step 2: Apply the rotation
The pattern follows a simple rotation. Each quarter is the one before it, rotated 90∘ clockwise. Imagine them arranged like a pinwheel.
Step 3: The answer
So the answer is (C) Figure C. To find the missing bottom-left quarter, we apply the 90∘ clockwise rotation to the quarter immediately preceding it in the sequence.
Which piece completes the pattern? (The missing quarter is marked ?)
Solution — answer A
Each quarter is the mirror image of the quarters beside it, across the middle lines. Mirroring the neighbouring quarters into the top-right corner gives option A.
4 steps · reveal one at a timeStep 1: Understand the Pattern
The question asks us to complete a pattern by finding its missing quarter. We need to identify the relationship between the existing parts of the figure to determine what the missing piece should be.
Step 2: Identify the Rule
The rule governing this pattern is that each quarter is a mirror image of the quarters adjacent to it. This reflection occurs across the central horizontal and vertical lines that divide the overall figure.
Step 3: Apply the Rule
To find the missing quarter, we must apply this mirroring rule. We need to consider the quarters next to the missing section and reflect them across the middle lines into the empty space.
Step 4: The answer
So the answer is (A) Figure A. Applying the mirror image rule to the neighbouring quarters leads directly to Figure A as the correct completion for the pattern.
Which piece completes the pattern? (The missing quarter is marked ?)
Solution — answer A
Each quarter is the one before it turned 90° clockwise, like a pinwheel. Turning the quarter before the top-right one gives option A.
4 steps · reveal one at a timeStep 1: Understand the Pattern
This question asks us to complete a pattern. We need to find the missing quarter, which is marked with a question mark, to complete the overall design.
Step 2: Identify the Rule
The pattern follows a consistent rule: each quarter is the one before it, but rotated. This creates a continuous flow, like a pinwheel.
Step 3: Determine the Rotation
The specific rotation is 90∘ clockwise. To find the missing piece, we must apply this 90∘ clockwise turn to the quarter immediately preceding the missing one.
Step 4: The answer
So the answer is (A) Figure A. Turning the quarter that comes before the missing top-right one by 90∘ clockwise will result in Figure A.
Which piece completes the pattern? (The missing quarter is marked ?)
Solution — answer D
Each quarter is the mirror image of the quarters beside it, across the middle lines. Mirroring the neighbouring quarters into the bottom-right corner gives option D.
4 steps · reveal one at a timeStep 1: Understand the pattern
The question asks us to complete a pattern by finding the missing quarter. We need to identify the relationship between the existing quarters to determine what the missing piece should be.
Step 2: Find the rule
The rule for this pattern is that each quarter is the mirror image of the quarters beside it, across the central horizontal and vertical lines. This means adjacent quarters are reflections of each other.
Step 3: Apply the rule
To find the missing bottom-right quarter, we must apply this mirroring rule. We need to mirror the quarter above it (top-right) and the quarter to its left (bottom-left) across the middle lines into the empty space.
Step 4: The answer
So the answer is (D) Figure D. Mirroring the neighbouring quarters into the bottom-right corner, according to the established rule, results in Figure D.
