Abstract Reasoning Flashcards

In an odd-one-out question, four shapes are squares and one is a rhombus with unequal diagonals. Which is the odd one out?

Answer: Rhombus with unequal diagonals

The rhombus with unequal diagonals is not a square, making it the odd one out.

A pattern rule states: the total number of sides across all shapes in each box remains constant at 12. A box has one square (4 sides) and one pentagon (5 sides). What shape completes the box?

Answer: Triangle

4 + 5 = 9 sides used; 12 − 9 = 3 sides needed, so a triangle completes the box.

Each row in an abstract reasoning question has shapes that increase in shading from 0% to 50% to 100%. The third shape in a row where the first is 0% shaded and the second is 50% shaded is:

Answer: 100% shaded

The pattern increases shading by 50% each step: 0% → 50% → 100%.

Set A figures all have internal symmetry (at least one line of symmetry). Set B figures have no lines of symmetry. Which set does a regular pentagon belong to?

Answer: Set A

A regular pentagon has 5 lines of symmetry, so it belongs to Set A.

In a series, each figure is produced by connecting every third dot on a circle: 12 dots → 4-pointed star, 15 dots → 5-pointed star, 18 dots → ?

Answer: 6-pointed star

With 18 dots and connecting every third, 18/3 = 6 points, producing a 6-pointed star.

A figure is reflected across the y-axis and then rotated 180°. Which single transformation is equivalent to this combination?

Answer: Reflection across the x-axis

Reflecting across the y-axis and then rotating 180° is equivalent to a single reflection across the x-axis.
