Geometry
the measure, in square units of the interior region of a 2-dimensional figure or the surface of a 3-dimentional figure
area
a(b+c) = a x b + a x c What property does this show?
distributive

percent
a selection that is chosen randomly (purely by chance, with no predictability)
random sample
set of whole numbers and their opposites and zero too
integers
The distance around a circle
circumference
a mathematical sentence that compares two unequal expressions using one of the symbols >, <, etc
inequality
an equation showing two ratios are equivalent
proportion
to state in advance on the basis of observation, experience, or scientific reason
prediction
the result of the division of one quantity by another, ie, the answer to a division problem.
quotient
Two angles that add up to 90 degrees
complementary angles
the replacement of variables in an algebraic expression with known values.
substitution
a ratio comparing two different units, like miles per hour
rate
an average, a single value that is used to represent a collection of data. Ex: mean, median, mode
Measure of Center Or Measure of central tendency
a decimal which has repeating digits or a repeating pattern of digits, like 1/3
repeating decimal

adjacent angle
a quantity that changes or can have different values, a symbol, usually a letter, ex: x
variable

scale drawing
a meausre of how much a collection of data is spread out, ex: range and quartiles
Measure of variation
the result of multiplying an interger by itself
square number

isosceles
mathematical operations that undo or reverse each other
inverse operations
a rate with a denominator of 1
unit rate
the absolute difference between the average of a data set and then then the average of those distances
MAD
the distance from a number to zero
absolute value
