Raven's Progressive Matrices Test Raven's Progressive Matrices Symmetry and Mirror Patterns 2 — Questions and Answers
Question 1: A Raven's matrix shows that each row is internally symmetric: the left and right cells mirror each other around the center cell. Rows 1 and 2 each show matching shapes on left and right. Row 3 has a medium square in the left cell. What must appear in the right cell of row 3?
- Large square
- Medium triangle
- Medium square (Correct answer)
- Small circle
Correct answer: Medium square
The internal left-right mirror rule requires the right cell to be the reflection of the left cell — a medium square reflected across a vertical axis is still a medium square.
Question 2: A Raven's matrix displays vertical reflective symmetry where column 1 mirrors column 3. If the center column shows shapes X, O, and triangle from top to bottom, what is the relationship between columns 1 and 3?
- Both columns are identical to the center column
- Columns 1 and 3 are mirror images of each other (Correct answer)
- Column 3 contains progressively larger versions of column 1
- Column 1 is a 90-degree rotation of column 3
Correct answer: Columns 1 and 3 are mirror images of each other
When the matrix has vertical symmetry with column 2 as the axis, columns 1 and 3 are reflections of each other while the center column serves as the dividing axis.
Question 3: A Raven's figure shows a crescent shape opening to the right, resembling ')'. If this figure is reflected across a vertical axis, what does the resulting mirror image look like?
- Crescent opening to the right ')'
- Crescent opening to the left '(' (Correct answer)
- Crescent opening upward
- Crescent opening downward
Correct answer: Crescent opening to the left '('
Reflecting ')' across a vertical axis reverses its horizontal orientation, producing '(' which opens to the left.
Question 4: Which of the following figures does NOT have bilateral (reflective) symmetry, making it most useful for distinguishing a figure from its true mirror image in Raven's matrices?
- A square
- A circle
- An equilateral triangle
- The letter F (Correct answer)
Correct answer: The letter F
The letter 'F' has no axis of symmetry and looks different from its mirror image, whereas squares, circles, and equilateral triangles all have at least one line of bilateral symmetry.
Question 5: A test-taker notices that the right cells in rows 1 and 2 of a Raven's matrix are horizontal reflections of their respective left cells. What is the most effective strategy for finding the missing piece in the right cell of row 3?
- Ignore the center column since it does not follow the reflection rule
- Apply the same reflection rule and mirror the left cell of row 3 (Correct answer)
- Search for a completely different rule that applies only to row 3
- Select the most visually complex answer option available
Correct answer: Apply the same reflection rule and mirror the left cell of row 3
Consistency is a fundamental feature of Raven's matrices — if the same reflection rule holds in rows 1 and 2, it applies equally to row 3.
Question 6: In a Raven's matrix where columns 1 and 3 are mirror reflections of each other (vertical bilateral symmetry), what role does the center column typically play?
- It contains the most complex shapes in the matrix
- It is always left blank to highlight the outer columns
- It acts as the axis of symmetry and is unaffected by the reflection (Correct answer)
- It is always identical to column 1
Correct answer: It acts as the axis of symmetry and is unaffected by the reflection
The center column lies directly on the vertical axis of symmetry and is not transformed by the reflection that swaps columns 1 and 3.
Question 7: In a Raven's matrix, a figure contains both an outer shape and internal details such as inner lines or dots. When this entire figure is mirrored across an axis, how do the internal details behave?
- The internal details disappear in the mirror image
- The internal details are mirrored just like the outer shape (Correct answer)
- The internal details remain in their original un-mirrored positions
- The internal details move to the center of the reflected shape
Correct answer: The internal details are mirrored just like the outer shape
Mirroring applies to the complete figure — both the outer boundary and all internal details are reflected across the axis simultaneously.
