A comparison of two numbers.
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.
The side of a right triangle, opposite the right angle.
The two sides of a right triangle that form the right angle.
Pythagorean triple
A set of three integers that satisfy the Pythagorean Theorem.

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.
A mathematical process that changes the shape or position of a geometric figure.
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 two-dimensional graph in which the points corresponding to two related factors (for example, smoking and life expectancy) are graphed and observed for correlation.
A consistent change over time in the statistical data representing a particular population.
The point at which a line or curve cuts across the y-axis.

random sample
A population sample chosen so that each member has the same probabilty of being selected.
Assigns exactly one output value to each input value.
In statistics, the difference between the largest and smallest values in a sample.
The answer to a mathematical problem. In algebra, a solution usually consists of a value or set of values for a variable.
A letter or other symbol that represents a number or set of numbers in an expression or an equation.
A mathematical sentence stating that two expressions are equal.
[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.
[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
