Net
A pattern that you can cut and fold to make a model of a solid shape
Base
The surface a solid object on, or the bottom line of a shape such as a triangle or rectangle. Can also be the number that gets multiplied when using an exponent
Expression
Numbers, symbols, and operators,= (such as + and x) grouped together that show the value of something
Scale
The ratio of the length in a drawing (or model) to the length on the real thing
A line with numbers placed in their correct position
Summary Statistics
The information that gives quick and simple description of the data
Diameter
The distance from one point on a circle through the center to another point on the circle. It is also the longest distance across the circle. And it is twice the radius
Legs
Either of the sides in a right triangle opposite an acute angle. The two shorter sides of the triangle
Infinity Many Solutions
When an equation has two variables, the set of ordered pairs that are the solution to the equation
Solution Set
Any value for x will make the equation true
Simulations
A way to model random events, such that simulated outcomes closely math real-world outcomes
Debit
An amount of money taken out of an account: The opposite of credit
Perimeter
The distance around a two-dimensional shape, but for a circle it is called the circumference
Part-To-Part
A ratio that represents the relationships of one part of a whole another part of the same whole
A visual model showing a fraction or fractions
Complementary Angles
Lines that are right angles (90 degrees) to each other
Like Terms
Terms whose variables (such as x and y) with any exponents (such as 2 in X2) are the same, and can be added together
Irrational Numbers
A real number that can NOT be made by dividing two integers (an integer has no fractional part). Its decimal also goes on forever without repeating.
Tip
An amount of money extra that is given to a worker such as a waiter or waitress who performs a service fro you. A common amount is 15% of cost of the meal or other service
Quantity
How much there is of something
Arrangement
A grouping of objects
Coordinates
A set of values that show an exact position. On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down
Perpendicular Lines
Two angles when they add up to 90 degrees (a right angle). They don't have to be next to be each other, just so long as the total is 90 degrees
Square Roots
A value that, when multiplied but itself, gives the number
