Plant Operator Selection System Figural Reasoning Flashcards

A sequence shows a triangle with its apex pointing up, then right, then down. Where does the apex point in the next figure?

Answer: Left

The apex rotates 90° clockwise each step: up→right→down→left.

A figure analogy: circle with horizontal line is to circle with vertical line as square with horizontal line is to ___.

Answer: Square with vertical line

The transformation rotates the internal line 90°, so a square with a horizontal line becomes a square with a vertical line.

A 3×3 matrix has one black cell, one gray cell, and one white cell per row and per column. The top-left is black, top-middle is gray, and middle-left is gray. What is the bottom-right cell?

Answer: Black

Each row and column must contain exactly one black, one gray, and one white cell; the bottom-right must be black to satisfy both constraints.

Which transformation turns a letter 'b' into a letter 'd'?

Answer: Reflection across a vertical axis

Reflecting 'b' across a vertical axis flips it horizontally, producing 'd'.

A series of figures shows a shaded region growing by one equal segment per step around a circle's perimeter: 1 segment shaded, 2 shaded, 3 shaded. If the circle has 6 equal segments, what fraction is shaded at step 5?

Answer: 5/6

At step 5, five of the six segments are shaded, giving 5/6.

Two figures are mirror images except one has an extra small triangle in the upper-right corner. What rule does this violate in a matching-pairs task?

Answer: Exact symmetry rule

A matching-pairs task requires the figures to be exact mirror images; the extra triangle breaks the exact symmetry rule.

A net has four triangles arranged around a central square. When folded, what 3D shape does it produce?

Answer: Square pyramid

Four triangular faces surrounding a square base fold up to form a square pyramid.
