alike

Describes two or more things that are the same in some important way. In analogy and classification questions, you look for what makes items alike before choosing an answer.

Related: different, same, belongs
different

Describes things that are not the same. Many questions ask you to find the one picture or word that is different from all the others in a group.

Related: alike, odd one out, belongs
same

Means exactly matching or identical in the way the question asks about. Young test takers are often asked to find the picture that is the same as a model picture.

Related: alike, matching, different
belongs

Means fits into a group because it shares a common feature with the other members. Classification questions ask which item belongs with the others and which one does not.

Related: category, odd one out, alike
category

A group of things that share something in common, such as animals, tools, or foods. Naming the category helps you decide which item fits and which does not.

Related: belongs, classify, odd one out
classify

To sort items into groups based on a shared feature. In pictorial and verbal questions, you classify by kind, use, color, shape, or another clear rule.

Related: category, belongs, sort
odd one out

The item in a group that does not share the feature the others have. Finding it requires naming what the rest have in common, not just guessing which looks unusual.

Related: belongs, category, different
matching

Pairing items that go together because they are the same or closely related. Matching questions may pair identical pictures, opposite words, or things that are used together.

Related: same, pair, goes together
pair

Two items that are grouped together because of a relationship. Recognizing the relationship in one pair helps you complete or choose a second pair with the same link.

Related: matching, analogy, goes together
goes together

Describes two things that are connected in everyday life, such as a shoe and a sock or a pencil and paper. These links are often based on use or function.

Related: pair, matching, function
opposite

A word or idea that means the reverse of another, such as hot and cold or up and down. Opposite questions ask you to pick the word that means the reverse.

Related: synonym, word meaning, relationship
synonym

A word that means nearly the same as another word, such as big and large. Synonym questions test whether you know the meaning of words you may not see every day.

Related: opposite, word meaning, vocabulary
word meaning

What a word stands for or refers to. Verbal reasoning questions often depend on knowing a word's meaning rather than how it sounds or how long it is.

Related: synonym, opposite, vocabulary
vocabulary

The set of words a person knows and can use. A strong vocabulary supports synonym, opposite, and classification questions because it helps you recognize how words relate.

Related: word meaning, synonym, context
analogy

A comparison that shows how two pairs of things share the same relationship, often written A is to B as C is to D. You solve it by naming the link in the first pair.

Related: relationship, pair, complete the pair
relationship

The connection between two items, such as part to whole, worker to tool, or cause to effect. Naming the relationship is the key step in analogy and pairing questions.

Related: analogy, pair, function
complete the pair

To choose the item that finishes a matching set so both pairs follow the same rule. The rule must hold for the first pair and the second pair equally.

Related: analogy, relationship, pair
sentence completion

Filling a missing word in a sentence so the whole sentence makes sense. You use the meaning of the other words as clues to choose the best fit.

Related: context, word meaning, best fit
context

The words around a blank or unfamiliar word that hint at its meaning. Using context helps you choose an answer that fits the sentence as a whole.

Related: sentence completion, vocabulary, best fit
best fit

The answer choice that works better than the others, even if more than one seems possible. You compare choices and pick the one that satisfies the rule most completely.

Related: sentence completion, context, eliminate
sequence

An ordered series in which each item follows a rule, such as growing by one each time. Finding the rule lets you predict what comes next or what is missing.

Related: pattern, next in series, rule
pattern

A repeated or predictable arrangement of shapes, colors, or positions. Noticing the repeating unit helps you continue the pattern correctly.

Related: sequence, rule, repeat
next in series

The item that should come after the last one shown, based on the rule of the series. You must identify the rule before choosing among the answer options.

Related: sequence, pattern, rule
rule

The consistent change or condition that governs a series or pattern, such as adding one side each step or rotating a shape. Every step in the series must obey it.

Related: pattern, sequence, rotate
rotate

To turn a shape around a point without flipping it over. Rotation questions ask you to track how far a shape turns and in which direction.

Related: flip, turn, rule
flip

To turn a shape over as if reflected in a mirror, so left and right or top and bottom swap. A flipped shape is not the same as a rotated shape.

Related: rotate, mirror image, turn
mirror image

The picture you see when a shape is reflected across a line. Mirror images reverse the shape in one direction while keeping its size and features.

Related: flip, symmetry, rotate
symmetry

A quality of a shape that can be folded along a line so both halves match exactly. Symmetry questions ask you to find the fold line or complete a matching half.

Related: mirror image, half, complete the shape
complete the shape

To choose the missing piece that makes a whole figure, often by matching edges, corners, or a line of symmetry. The piece must fit without gaps or overlaps.

Related: symmetry, half, piece
piece

One part of a larger figure that has been cut or divided. Questions may ask which piece, when added, finishes the figure exactly.

Related: complete the shape, whole, fit
whole

The complete figure made when all its parts are put together. Understanding the whole helps you judge whether a piece belongs or is the wrong size and shape.

Related: piece, complete the shape, fit
figure

Any drawn shape or design used in a question, such as a triangle, star, or combined form. Figural questions ask you to compare, transform, or complete figures.

Related: shape, pattern, whole
shape

The outline or form of a figure, described by features such as number of sides, curves, and corners. Noticing shape features is basic to pictorial and figural questions.

Related: figure, size, feature
size

How big or small an item is compared with others. Size is one of the features that can change in a pattern or distinguish the odd item in a group.

Related: shape, feature, pattern
feature

A noticeable quality of an item, such as color, shape, size, position, or number. Comparing features is how you find what items share and what changes.

Related: sort, shape, size
sort

To arrange items into groups by a chosen feature such as color or kind. Sorting questions require you to apply one clear rule to every item.

Related: classify, feature, category
function

The job or use of an object, such as a cup holding liquid or scissors cutting. Function links are common in pairing and classification questions.

Related: goes together, relationship, belongs
eliminate

To rule out answer choices that clearly break the rule. Eliminating wrong choices first makes it easier to pick the remaining correct answer.
