Question 1

Complete the 3×3 matrix: ◆ ◆ ◆ ◇ ◇ ◇ ○ ○ ? What symbol replaces '?' ?
Each row contains the same symbol. Row 3 has '○' in cols 1-2, so col 3 must also be '○'.
matrix, grid, pattern, logic

Question 2

Geometric Pattern: Triangular grid Current state: Top 6 triangles complete, bottom 2 missing What element is needed for completion?
In triangular grid, all positions must follow the same geometric rule. The missing element is the two bottom triangles to maintain consistency.
geometric, spatial, tessellation

Question 3

Pattern: ⭐ Star pattern Missing: bottom quarter in ⭐ Star pattern Missing: bottom quarter What symbol completes the pattern?
In a symmetrical ⭐ star pattern, all four quarters must be identical. The missing bottom quarter should be a star like the others.
missing, quarter, basic, symmetry

Question 4

Find the odd one and complete: ● ● □ ? What should replace '?' to make a consistent pattern?
□ is the odd one out because it's different from ●. To make all elements consistent, replace '?' with ●.
odd-one-out, consistency, pattern

Question 5

Pattern: Leaf pattern Current state: right: 4 veins, left: 3 veins What is needed to complete the symmetrical pattern?
For perfect symmetry in a leaf pattern, both sides must match. Currently right: 4 veins, left: 3 veins, so we need to add one vein.
symmetry, mirror, completion

Question 6

Size progression pattern: ⚪ (tiny) → ○ (medium) → ● (large) → ? What size comes next?
Size increases progressively: tiny → small → medium → large. The missing size is small (◯).
size, progression, sequence

Question 7

Complete the 3×3 matrix: ▲ ● ▲ ● ▲ ● ▲ ● ? What symbol replaces '?' ?
Pattern alternates ▲ → ● → ▲ in each row. Row 3 follows: ▲, ●, so last is ▲.
matrix, grid, pattern, logic

Question 8

Complete the 3×3 matrix: △ ● △ ● △ ● △ ● ? What symbol replaces '?' ?
Pattern alternates △ → ● → △ in each row. Row 3 follows: △, ●, so last is △.
matrix, grid, pattern, logic

Question 9

Pattern: Pinwheel with 90° rotational symmetry Current: blades at: NE, NW, SW Missing: SE position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The SE position needs the same element as the others → SE blade.
rotation, symmetry, spatial

Question 10

Find the odd one and complete: ? □ △ □ What should replace '?' to make a consistent pattern?
△ is the odd one out because it's different from □. To make all elements consistent, replace '?' with □.
odd-one-out, consistency, pattern

Question 11

Geometric Pattern: Triangular grid Current state: Top 6 triangles complete, bottom 2 missing What element is needed for completion?
In triangular grid, all positions must follow the same geometric rule. The missing element is the two bottom triangles to maintain consistency.
geometric, spatial, tessellation

Question 12

Pattern: Leaf pattern Current state: right: 4 veins, left: 3 veins What is needed to complete the symmetrical pattern?
For perfect symmetry in a leaf pattern, both sides must match. Currently right: 4 veins, left: 3 veins, so we need to add one vein.
symmetry, mirror, completion

Question 13

3D/Perspective Pattern: Cube Missing: Missing back-right edge What completes the perspective drawing?
In perspective drawing, all parallel lines converge to vanishing points. The Missing back-right edge must follow these same convergence rules → hidden back edge.
perspective, 3d, spatial

Question 14

Complex Pattern: Grid 4×4 Missing elements: Missing 4 corner cells How should the pattern be completed?
In grid 4×4, the pattern logic applies consistently. The Missing 4 corner cells must be filled with corner cells to maintain integrity.
multiple, complex, grid

Question 15

Pattern: Diamond with 90° rotational symmetry Current: corners filled: top, left, right Missing: bottom position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The bottom position needs the same element as the others → bottom corner.
rotation, symmetry, spatial

Question 16

Complete the analogy: ● : ○ :: ■ : ? (Relation: solid to hollow)
The relation is 'solid to hollow'. Since ● becomes ○, then ■ becomes □ (hollow square).
analogy, relation, abstract

Question 17

Pattern: ▲ Triangle pattern Missing: bottom-right quarter in ▲ Triangle pattern Missing: bottom-right quarter What symbol completes the pattern?
In a symmetrical ▲ triangle pattern, all four quarters must be identical. The missing bottom-right quarter should be a solid triangle like the others.
missing, quarter, basic, symmetry

Question 18

Complete the analogy: ↑ : → :: ↓ : ? (Relation: rotate 90° clockwise)
The relation is 'rotate 90° clockwise'. Since ↑ becomes →, then ↓ becomes ← (left arrow).
analogy, relation, abstract

Question 19

Pattern: Cross with 90° rotational symmetry Current: arms at: top, left, right Missing: bottom position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The bottom position needs the same element as the others → bottom arm.
rotation, symmetry, spatial

Question 20

3D/Perspective Pattern: Isometric shape Missing: Missing top face What completes the perspective drawing?
In perspective drawing, all parallel lines converge to vanishing points. The Missing top face must follow these same convergence rules → top face.
perspective, 3d, spatial
