not exact,but close enough to be reasonably correct
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)
not exact, but close to exact amount
(v.) to find out by adding, subtracting, multiplying, or dividing; to figure out by reason or logic
the amount a container can hold
The distance around a circle
same shape and same size
following in order or without interruption
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
Two sides that are in the same position in the original and the image.
Facts, figures, and other evidence gathered through observations.
a line that slants; connecting two non-adjoining vertices
To enlarge in all directions.

line along which two planes of a solid figure meet
Making a new image that is bigger than the original figure
to figure out; to determine roughly; to calculate; a rough guess as to size, value, etc.; an opinion
the part of a number sentence that combines numbers and operations, but doesn't have an equal sign.
to produce or create
not correct or reasonable
a figure with noncongruent sides and interior angles
the sum of the areas of the lateral faces of a solid; go around the sides, not the bases
The average (add all values and divide by how many there are)
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.
the number that appears the most times
the product of two factors
generlization that is used to describe any given number in a sequence
the point of intersection of coordinate axes
lines that will never meet, no matter how long you stretch them (like railroad tracks!)
the distance around the outside (add up all the sides)

answer to a multiplication problem
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
the answer of a division problem

to find this, you subtract the smallest number from the biggest
a ratio is a comparison of two quantities; it is sometimes expressed as a fraction.
Making a new image that is smaller than the original figure
a transformation that produces the miror image of a geometric figure over a line of reflection

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'.
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.
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
a group of things of the same kind that belong together and are so used
same shape, but different size
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
Some transformations, like dilation, affect the size of the figure. Other transformations are translations, reflections, and rotations.
