NNAT Matrix Reasoning 3 — Questions and Answers
Question 1: In a matrix, shapes in the left column are solid and shapes in the right column are outlined (unfilled). A solid pentagon appears in column 1. What appears in column 2 of the same row?
- an outlined pentagon (Correct answer)
- a solid pentagon
- an outlined hexagon
- a solid circle
Correct answer: an outlined pentagon
The rule changes solid shapes to outlined versions of the same shape moving right.
Question 2: A 3x3 matrix has shapes that grow larger from top to bottom in each column. The top row shows small shapes and the middle row shows medium shapes. What size shapes fill the bottom row?
- large (Correct answer)
- small
- medium
- extra-small
Correct answer: large
The size progression small to medium to large places large shapes in the bottom row.
Question 3: Each row in a matrix contains exactly one circle, one square, and one triangle in different columns. Row 1: circle col 1, square col 2, triangle col 3. Row 2: triangle col 1, circle col 2, square col 3. Where is the circle in row 3?
- column 3 (Correct answer)
- column 1
- column 2
- it repeats column 2
Correct answer: column 3
The circle has been in col 1 and col 2, so by elimination it must appear in column 3 in row 3.
Question 4: A matrix shows shapes that are reflected horizontally as you move right across a row. A right-pointing arrow is in column 1. What does column 3 show after two horizontal reflections?
- a right-pointing arrow (Correct answer)
- a left-pointing arrow
- an up-pointing arrow
- a down-pointing arrow
Correct answer: a right-pointing arrow
Two horizontal reflections cancel each other out, returning the arrow to its original right-pointing direction.
Question 5: A matrix row shows: star with 5 points, star with 6 points, star with 7 points. The next row shows: star with 4 points, star with 5 points, and what in the third cell?
- star with 6 points (Correct answer)
- star with 4 points
- star with 8 points
- star with 3 points
Correct answer: star with 6 points
Each row adds one point per column; the second row starts at 4 and increases, making the third cell a 6-point star.
Question 6: In a NNAT-style matrix, the top-left, center, and bottom-right cells are identical, and the top-right and bottom-left cells are also identical but different from the first group. This pattern reflects which type of symmetry?
- diagonal symmetry (Correct answer)
- row repetition
- column progression
- rotational asymmetry
Correct answer: diagonal symmetry
When matching cells fall along diagonals of a matrix, this reflects diagonal symmetry in the pattern.
Question 7: A matrix contains overlapping shapes where the number of overlaps increases by one across each row (1, 2, 3) and down each column (1, 2, 3) additively. Using the formula cell = (row-1) + (col-1) + 1, how many shapes are at row 3, column 3?
- 5 (Correct answer)
- 9
- 6
- 3
Correct answer: 5
Using the formula: (3-1) + (3-1) + 1 = 2 + 2 + 1 = 5 shapes.
NNAT Matrix Reasoning 3
In a matrix, shapes in the left column are solid and shapes in the right column are outlined (unfilled).
A solid pentagon appears in column 1.
What appears in column 2 of the same row?
