analogy

A comparison stating that one pair of items relates in the same way as a second pair, so the missing item can be found by applying the first pair's rule to the second.

Related: relationship rule, A is to B as C is to D
A is to B as C is to D

The standard written layout of an analogy item, where the link between the first two items must be copied to complete the second pair.

Related: analogy, relationship rule
relationship rule

The single transformation, such as adding a side, rotating, or darkening, that connects the first pair of an analogy and must also connect the second pair.

Related: analogy, consistent transformation
consistent transformation

A change applied in exactly the same way to both halves of an analogy, so the answer choice must show the identical operation rather than a similar-looking one.

Related: relationship rule, distractor
distractor

An answer choice built to look plausible but that breaks the item's rule in some detail, such as wrong size, wrong shading, or wrong position.

Related: elimination, consistent transformation
elimination

The strategy of ruling out answer choices that clearly violate the rule, narrowing the field before choosing among the remaining options.

Related: distractor, verification
verification

Checking a chosen answer by applying the rule to it a second time to confirm it fits every part of the pattern, not just the most obvious part.

Related: elimination, relationship rule
pattern completion

Finding the missing piece of a design in which a large square has a section removed and the candidate must select the piece that restores the whole design.

Related: missing piece, continuity of lines
missing piece

The cut-out section of a larger design that the candidate must supply, matching lines, shading, and shapes at the edges of the gap.

Related: pattern completion, edge matching
edge matching

Comparing the borders of a candidate piece with the borders of the gap so that lines and shaded regions meet without breaks, shifts, or overlaps.

Related: missing piece, continuity of lines
continuity of lines

The requirement that a line entering the gap on one side must leave the piece at the matching point on the opposite side, with the same slope.

Related: edge matching, alignment
alignment

Correct positioning of shapes and lines so that elements inside the missing piece sit exactly where the surrounding design requires them.

Related: continuity of lines, symmetry
symmetry

A design property in which one half mirrors or repeats the other, often used to infer what the missing section of a pattern must contain.

Related: alignment, rotational symmetry
rotational symmetry

A property in which a figure looks unchanged after being turned by some angle less than a full turn, useful for predicting repeated elements around a center.

Related: symmetry, rotation
grid overlay

A mental or drawn set of rows and columns placed over a design so that positions of shapes and lines can be described and compared precisely.

Related: alignment, position
serial reasoning

Working out the rule that governs a left-to-right or top-to-bottom sequence of figures, then choosing the figure that continues the sequence correctly.

Related: sequence, progression rule
sequence

An ordered series of figures in which each item differs from the previous one by a rule that stays the same throughout the series.

Related: serial reasoning, progression rule
progression rule

The repeating change, such as gaining a shape, shifting a position, or alternating shading, that generates each successive figure in a series.

Related: sequence, step size
step size

The amount of change between consecutive figures in a series, for example one added side, one position moved, or one shade darkened.

Related: progression rule, counting pattern
counting pattern

A numerical rule in a series, such as sides increasing by one each time or shapes increasing 1, 2, 3, that predicts the next figure's count.

Related: step size, progression rule
alternating pattern

A series in which two rules take turns, so odd-positioned figures follow one rule and even-positioned figures follow another.

Related: sequence, progression rule
repeating cycle

A series in which a fixed group of figures or attributes recurs in the same order, so the next item is found by continuing the cycle.

Related: alternating pattern, sequence
spatial visualization

Mentally moving, turning, folding, or assembling shapes to determine how a figure looks after a change in position or orientation.

Related: mental rotation, folding
mental rotation

Imagining a figure turned by a stated angle, then identifying which answer choice shows the same figure in that new orientation.

Related: rotation, spatial visualization
rotation

Turning a figure around a fixed point by a given angle, such as 90 degrees clockwise, without flipping it over.

Related: mental rotation, reflection
reflection

Flipping a figure across a line so it becomes a mirror image, which changes handedness and cannot be produced by rotation alone.

Related: rotation, mirror image
mirror image

The result of reflecting a figure across a line, where left and right are exchanged and the figure's orientation is reversed.

Related: reflection, rotation
translation

Sliding a figure to a new position without rotating or flipping it, so its orientation and shape stay exactly the same.

Related: rotation, position
folding

Bending paper or a shape along a line so one part lies over another, used to predict the pattern of holes or creases that results.

Related: unfolding, punch holes
unfolding

Opening a folded shape back out to see where punched holes or creases appear, with each hole mirrored across every fold line it crossed.

Related: folding, punch holes
punch holes

Holes made through folded paper that appear in multiple places when the paper is opened, mirrored across each fold line.

Related: folding, unfolding
paper folding

A spatial task in which a sheet is folded one or more times, holes are punched, and the candidate identifies the unfolded sheet's hole pattern.

Related: folding, unfolding
orientation

The direction a figure faces, described by which way its top, point, or opening is turned relative to the page.

Related: rotation, mental rotation
position

Where a figure sits within its frame, such as top-left or center, which may change while shape and orientation stay the same.

Related: translation, grid overlay
shape attribute

A feature of a figure such as number of sides, size, color, shading, or outline style that can change independently within a pattern.

Related: progression rule, counting pattern
shading

The fill of a shape, such as white, gray, black, or hatched, which often follows its own rule separate from shape or position.

Related: shape attribute, alternating pattern
same figure, different view

An answer choice showing a figure that has been rotated rather than altered, so it is the same shape seen from another angle.

Related: mental rotation, orientation
odd one out

A task in which all but one figure share a common property, and the candidate identifies the figure that does not belong.
