In a 2x3 matrix, shapes transform across columns: Column 1 has a small circle and a large circle. Column 2 has a small square and a large square. What should Column 3 contain?

Answer: Small triangle and large triangle

The pattern introduces a new shape in each column while maintaining the size relationship (small on top, large on bottom). Following circle and square, the next logical shape is a triangle. The size ordering remains consistent.

A 3x3 matrix has lines in each cell. Row 1: 1 horizontal, 1 vertical, 1 diagonal. Row 2: 2 horizontal, 2 vertical, 2 diagonal. How many diagonal lines should appear in the last cell of Row 3?

Answer: 3

The number of lines increases by one per row (Row 1 has 1 of each type, Row 2 has 2 of each type). Row 3 should have 3 of each line type, so the last cell has 3 diagonal lines.

In a matrix, each row contains three shapes with different fill patterns. If Row 1 has: solid circle, striped square, empty triangle, and Row 2 has: striped circle, empty square, solid triangle, what fill does the circle in Row 3 have?

Answer: Empty

Each shape cycles through fills: circle goes solid→striped→empty, square goes striped→empty→solid, triangle goes empty→solid→striped. The circle in Row 3 is empty. Each shape independently rotates through the three fill types.

A 3x3 matrix shows geometric figures where the number of sides increases along each row by 1 and down each column by 1. If cell (1,1) is a triangle (3 sides), what shape is in cell (3,3)?

Answer: Heptagon (7 sides)

Starting from 3 sides at (1,1), moving right adds 1 side and moving down adds 1 side. Cell (3,3) = 3 + 2 (right) + 2 (down) = 7 sides, which is a heptagon. The matrix creates a systematic grid of increasing polygon complexity.

In a matrix puzzle, each cell contains a shape that is the XOR (symmetric difference) of the shapes in the same row's first two cells. Row 1: circle, square → circle-with-square-cutout. Row 2: triangle, circle → triangle-with-circle-cutout. Row 3: square, triangle → ?

Answer: Square with triangle cutout

The third cell in each row combines the two shapes from that row using a symmetric difference operation: the first shape with the second shape cut out of it. Row 3 gives a square with a triangle-shaped cutout.

A matrix uses color mixing rules. Row 1: Red, Blue, Purple. Row 2: Blue, Yellow, Green. Row 3: Red, Yellow, ?. What color completes the matrix?

Answer: Orange

The third column shows the result of mixing the colors from the first two columns: red+blue=purple, blue+yellow=green, red+yellow=orange. This uses standard color mixing theory as the logical rule.
