###
annual

occurring once each year ; yearly

###
approximate

not exact,but close enough to be reasonably correct

###
base

a number multiplied by itself as indicated from the exponent (the base number is to be multiplied by itself as many times as the exponent says)

###
best estimate

not exact, but close to exact amount

###
calculate

(v.) to find out by adding, subtracting, multiplying, or dividing; to figure out by reason or logic

###
capacity

the amount a container can hold

###
circumference

The distance around a circle

###
congruent

same shape and same size

###
consecutive

following in order or without interruption

###
coordinate plane

a grid formed by two number lines that intersect at their zero points. The two axes meet at the ordered pair (0, 0) and divide the plane into four quadrants

###
corresponding sides

Two sides that are in the same position in the original and the image.

###
data

Facts, figures, and other evidence gathered through observations.

###
diagonal

a line that slants; connecting two non-adjoining vertices

###
dilate

To enlarge in all directions.

###
dimensions

length, width, and height

###
doubled

multiplyed by two

###
edge

line along which two planes of a solid figure meet

###
enlargement

Making a new image that is bigger than the original figure

###
estimate

to figure out; to determine roughly; to calculate; a rough guess as to size, value, etc.; an opinion

###
expression

the part of a number sentence that combines numbers and operations, but doesn't have an equal sign.

###
generate

to produce or create

###
inaccurate

not correct or reasonable

###
irregular figure

a figure with noncongruent sides and interior angles

###
lateral area

the sum of the areas of the lateral faces of a solid; go around the sides, not the bases

###
mean

The average (add all values and divide by how many there are)

###
median

The middle number in a list. Put numbers in order FIRST. If there are 2 numbers in the middle, add them and divide by 2.

###
mode

the number that appears the most times

###
multiples

the product of two factors

###
nth term

generlization that is used to describe any given number in a sequence

###
origin

the point of intersection of coordinate axes

###
parallel

lines that will never meet, no matter how long you stretch them (like railroad tracks!)

###
perimeter

the distance around the outside (add up all the sides)

###
potential

posible, able to happen, something that can develop

###
prism

has to have 2 bases that are identical and all other faces are rectangles

###
product

answer to a multiplication problem

###
pyramid

Three dimensional figure with triangluar faces that meet at a vertex. The edges form a point at the top. Named for the shape of the base

###
quotient

the answer of a division problem

###
random

by chance, not planned or prearranged; irregular

###
range

to find this, you subtract the smallest number from the biggest

###
ratios

a ratio is a comparison of two quantities; it is sometimes expressed as a fraction.

###
reduction

Making a new image that is smaller than the original figure

###
reflection

a transformation that produces the miror image of a geometric figure over a line of reflection

###
revenue

Total Amount of money a business takes in during a given period selling goods and services

###
rotation

The original image is the square labeled ABDC. The image after rotating the square 45 degrees (counterclockwise) about its center gives the square labeled A'B'D'C'.

###
scale factor

In a transformation, the number by which the distance of the preimage from the center of dilation is multiplied to determine the distance of the image point from its center.

###
scientific notation

There are two parts of the scientific notation. The first part is a number between 1-10. The second part is a power of ten. example: 2.25 * 10^4

###
set

a group of things of the same kind that belong together and are so used

###
similar

same shape, but different size

###
squared

Any number or variable with a 2 for an exponent is said to be squared.

###
total surface area

the sum of all the areas of the faces and bases of a solid figure

###
transformation

Some transformations, like dilation, affect the size of the figure. Other transformations are translations, reflections, and rotations.

###
trend

a pattern over time, such as increasing, decreasing, or staying the same, that is shown by data in part or all of the graph

###
valid

well-supported by facts; true

###
vertex

The point where 2 rays meet in an angle or 2 or more line segments meet in plane figures, or 3 or more sides meet in solid figures

###
vertical

line going up and down
