Matrix Reasoning Flashcards

A 3x3 matrix has a rule where the total number of sides of all shapes in each row equals 12. Row 2 has a hexagon (6 sides) and a triangle (3 sides). What shape completes row 2?

Answer: a triangle

12 minus 6 minus 3 equals 3 sides needed, so a triangle completes the row.

In a matrix, row 2 shows double the quantity of shapes compared to row 1, and row 3 shows double row 2. Row 1 has 1 shape. How many shapes does row 3 have?

Answer: 4

Doubling 1 gives 2 for row 2, and doubling 2 gives 4 for row 3.

A matrix uses an XOR visual rule: column 3 shows only the non-overlapping regions of columns 1 and 2. Column 1 has a circle on the left half; column 2 has a circle on the right half. What does column 3 show?

Answer: a full circle

Since the left-half circle and right-half circle do not overlap, both halves appear in column 3, forming a complete circle.

A matrix pattern shows each shape rotated 45 degrees clockwise as you move right. Starting with a square oriented normally, what does it look like after three 45-degree clockwise rotations?

Answer: a square rotated 135 degrees, resembling a diamond tilted sideways

Three 45-degree rotations equal 135 degrees total, giving a square tilted 135 degrees from its original position.

A matrix rule states that each row's center cell is always the average size of the left and right cells. The left cell has a large shape and the right cell has a small shape. What size is the center cell?

Answer: medium

The average size between large and small is medium, so the center cell contains a medium-sized shape.

In a NNAT matrix, frame thickness follows a row rule: thin in row 1, medium in row 2, thick in row 3. A shape with a thin frame appears in column 2. In which row is it located?

Answer: row 1

Thin frames belong exclusively to row 1 based on the stated progression rule.

When solving a NNAT matrix, the missing cell's row neighbors are both striped triangles and its column neighbors are both solid triangles. Which answer choice best fits both rules?

Answer: a striped triangle

The shape must be a triangle (consistent with both row and column neighbors), and the row rule for striping takes precedence for the fill attribute.
