The distance around a circle, calculated by multiplying the diameter by the value pi.


polygon

A simple, closed plane figure, having three or more line segments as sides.


prism

A solid figure that has two parallel, congruent polygonal facs (called bases).


cube

A solid figure with six square faces.


cylinder

A solid shape with parallel circular bases.


similar figures

Have the same shape but are not necessarily the same size.


ratio

A comparison of two numbers.


proportion

A statement that two ratios are equal.


scale drawing

A proportionally correct drawing of an object or area at actual, enlarged, or reduced size.


Pythagorean Theorem

A mathematical idea stating that the sum of the squared lengths of the two shorter sides of a right triangle is equal to the squared length of the hypotenuse.


right triangle

A triangle with one right angle.


hypotenuse

The side of a right triangle, opposite the right angle.


legs

The two sides of a right triangle that form the right angle.


Pythagorean triple

A set of three integers that satisfy the Pythagorean Theorem.


area

The size of a surface, usually expressed in square units.


volume

The space occupied by a solid, measured in cubic units.


perimeter

The distance around the outside of a closed figure.


square

To multiply a number by itself; shown by the exponent 2.


irrational numbers

The set of all numbers that cannot be expressed as finite or repeating decimals.


transformation

A mathematical process that changes the shape or position of a geometric figure.


scale

The ratio between the actual size of an object and proportional representation.


scale factor

The factor by which all the components of an object are multiplied in order to create a proportional enlargement.


scatter plot

A twodimensional graph in which the points corresponding to two related factors (for example, smoking and life expectancy) are graphed and observed for correlation.


trend

A consistent change over time in the statistical data representing a particular population.


yintercept

The point at which a line or curve cuts across the yaxis.


xintercept

The point at which a line or curve cuts across the xaxis.


ordered pair

Two numbers that tell the xcoordinate and ycoordinate of a point.


slope

[1]A way of describing the steepness of a line, ramp, hill, and so on;
[2]The ratio of the rise to the run. 

measures of central tendancy

Numbers or pieces of data that can represent the whole set of data.


mean

The sum of the numbers in a set of data divided by the number of pieces of data in the data set.


median

The middle number in a set of data when the data are arranged in numerical order. If the data has an even number, the median is the mean of the two middle numbers.


mode

The number(s) or item(s) that appear most often in a set of data.


range

In statistics, the difference between the largest and smallest values in a sample.


sample

A finite subset of a population, used for statistical analysis.


random sample

A population sample chosen so that each member has the same probabilty of being selected.


function

Assigns exactly one output value to each input value.


range

In statistics, the difference between the largest and smallest values in a sample.


solution

The answer to a mathematical problem. In algebra, a solution usually consists of a value or set of values for a variable.


variable

A letter or other symbol that represents a number or set of numbers in an expression or an equation.


equation

A mathematical sentence stating that two expressions are equal.


intercept

[1]The cutting of a line, curve, or surface by another line, curve, or surface;
[2]The point at which a line or curve cuts across a given axis. 

slope

[1]A way of describing the steepness of a line, ramp, hill, and so on;
[2]The ratio of the rise to the run. 

commutative property

The mathematical rule that states that the order in which numbers are added or multiplied has no effect on the sum or product.


associative property

A rule that states that the sum or product of a set of numbers is the same, no matter how the numbers are grouped.


additive inverse

A number that when added to given number results in a sum of zero.


multiplicative inverse

The number for any given number that will yield 1 when the two are multiplied, same as reciprocal.


nonlinear function

A function that does not have a constant rate of change. The graph of a nonlinear function is not a straight line.


linear function

A function in which the graph of the solutions forms a line.

Two angles are supplementary if the sum of their measures is 180°.


coordinate plane

A plane in which a horizontal number line and vertical number line intersect at their zero points.


dependent variable

The variable for the output of a function.


independent variable

The variable for the input of a function.


outlier
