32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Synonym analogy
- Two word pairs in which both members of each pair mean nearly the same thing, as in happy:joyful :: begin:start; the linking bridge is 'means the same as.'
- Antonym analogy
- Pairs whose members have opposite meanings, such as hot:cold :: ancient:modern; the correct answer must reverse in the same direction as the stem pair.
- Part-to-whole analogy
- The first term is a component of the second, as in wheel:car :: page:book; the answer must keep the smaller part before the larger whole.
- Cause-and-effect analogy
- The first term produces the second, as in rain:flood :: spark:fire; the answer must keep the direction from cause to result.
- Function analogy
- The first term is an object and the second is its purpose, as in knife:cut :: pen:write; the answer must express a use rather than a description.
- Degree analogy
- The two terms differ only in intensity along one scale, as in warm:hot :: cool:cold; the answer must move the same direction by a similar step.
- Abstruse
- Adjective meaning difficult to understand or obscure; an abstruse explanation is one that most listeners cannot follow without extra background.
- Laconic
- Adjective describing speech that is very brief and sparing in words, sometimes to the point of bluntness; a laconic answer is a short one.
- Garrulous
- Adjective for a person who talks a great deal, often at length about trivial matters; it is the opposite of taciturn and of laconic.
- Frugal
- Adjective meaning economical and careful with money or resources; a frugal buyer purchases only what is necessary and avoids waste.
- Percent change formula
- Percent change equals the new value minus the old value, divided by the old value, then multiplied by 100; a negative result is a decrease.
- Average speed
- Average speed for an entire trip equals total distance traveled divided by total time taken, not the average of the separate leg speeds.
- Combined work rate
- If one worker completes a job in a hours and another in b hours, working together they finish in ab divided by (a + b) hours.
- Simple interest formula
- Interest equals principal times annual rate times time in years, I = Prt; for six months use t = 0.5, then add interest to principal for the total.
- Trapezoid area formula
- Area equals one-half the sum of the two parallel bases multiplied by the height between them: A = ½(b₁ + b₂)h.
- Cylinder volume formula
- Volume equals the area of the circular base times the height: V = πr²h, where r is the base radius and h the height.
- 3-4-5 right triangle
- A right triangle with legs 3 and 4 has hypotenuse 5; any whole-number multiple such as 6-8-10 or 9-12-15 is also a right triangle.
- 30-60-90 triangle
- The sides are in ratio x, x√3, and 2x; the shortest side faces the 30° angle and the hypotenuse is twice the shortest side.
- Median versus mean
- The median is the middle value of an ordered list and ignores extremes; the mean is the sum divided by the count and is pulled by outliers.
- Independent event probability
- The probability that two independent events both occur equals the product of their separate probabilities; two coin flips both heads is ½ × ½ = ¼.
- Block counting total
- The total number of blocks equals the sum of the heights of every column, since each column rests on the ground and contains no hidden gaps.
- Cube faces and edges
- A cube has 6 square faces, 12 edges, and 8 vertices; each face touches four other faces and is parallel to exactly one opposite face.
- Hidden figures
- The target shape is embedded at the same size and orientation as shown; trace straight line segments through the drawing to find its outline.
- Table reading procedure
- Find the row label and the column label, then read the cell where they intersect; check the units stated in the header before choosing an answer.
- Altimeter reading
- On the altimeter the short hand indicates thousands of feet and the long hand hundreds; one full sweep of the long hand equals 1,000 feet.
- Airspeed indicator
- The airspeed dial is marked in knots; the white arc is the flap-operating range, the green arc the normal range, and the red line maximum speed.
- Attitude indicator
- The attitude indicator shows pitch and bank: the horizon bar stays level with the real horizon while the miniature aircraft tilts with the airplane.
- Vertical speed indicator
- The VSI shows rate of climb or descent in feet per minute; a needle above the zero mark means climbing, below it means descending.
- Bernoulli lift
- Air moving faster over the curved upper surface of a wing has lower pressure than slower air below, so the pressure difference pushes the wing upward.
- Newton's second law
- Net force equals mass times acceleration, F = ma; at constant mass, doubling the net force doubles the acceleration produced.
- Density formula
- Density equals mass divided by volume; an object of 100 grams occupying 20 cubic centimeters has a density of 5 grams per cubic centimeter.
- Ohm's law
- Voltage equals current times resistance, V = IR; at a fixed voltage, doubling the resistance halves the current through the circuit.
