CCAT Spatial Reasoning: Odd One Out 5 — Questions and Answers
Question 1: Three figures are open shapes (C, U, L) and one is a closed shape (O). Which is the odd one out?
- C shape
- U shape
- L shape
- O shape (Correct answer)
Correct answer: O shape
The O shape is a fully closed figure, while C, U, and L are all open shapes.
Question 2: Four tiles each contain a pattern of stripes: horizontal, vertical, diagonal left, and one with a solid fill. Which is the odd one out?
- Horizontal stripes
- Vertical stripes
- Diagonal stripes
- Solid fill (Correct answer)
Correct answer: Solid fill
The solid fill tile has no line pattern at all, unlike the other three.
Question 3: Which of the following is NOT a quadrilateral: rectangle, rhombus, trapezoid, or pentagon?
- Rectangle
- Rhombus
- Trapezoid
- Pentagon (Correct answer)
Correct answer: Pentagon
A pentagon has 5 sides, while rectangles, rhombuses, and trapezoids all have exactly 4 sides.
Question 4: Four sequences show shapes growing by adding one side each step (triangle→square→pentagon→hexagon), except one sequence that skips a step. Which sequence is the odd one out if Sequence C jumps from triangle directly to pentagon?
- Sequence A (no skip)
- Sequence B (no skip)
- Sequence C (skips square) (Correct answer)
- Sequence D (no skip)
Correct answer: Sequence C (skips square)
Sequence C skips the square (4 sides), breaking the pattern of adding one side per step.
Question 5: Three shapes are concave polygons (have an indentation) and one is a convex polygon with no indentations. Which is the odd one out?
- Arrow shape (concave)
- Star shape (concave)
- Cross shape (concave)
- Regular hexagon (convex) (Correct answer)
Correct answer: Regular hexagon (convex)
The regular hexagon is convex with no inward-pointing vertices, unlike the other three shapes.
Question 6: Four block letter shapes are shown from above: T, L, I, and X. Which letter shape has the MOST right-angle corners?
- T shape
- L shape
- I shape
- X shape (Correct answer)
Correct answer: X shape
An X shape has 12 interior and exterior right-angle corners, more than T (8), L (4), or I (8).
Question 7: Four figures show pairs of overlapping shapes: three pairs overlap partially (sharing an area), but one pair of shapes is entirely separate with no overlap. Which is the odd one out?
- Pair A (partial overlap)
- Pair B (partial overlap)
- Pair C (no overlap) (Correct answer)
- Pair D (partial overlap)
Correct answer: Pair C (no overlap)
Pair C has no overlapping area between the two shapes, unlike the other three pairs.
