A fractional equation where all or most of the terms are different variables.
Back
Angle Bisector
Front
A ray, line, or segment that passes through the vertex of an angle and divides the angle into two equal parts.
Back
Area of a Square
Front
The product of one of the sides of the square squared (A = S squared); or found by multiplying the length and the width
Back
Average
Front
The sum of a set of values divided by the number of values
Back
Arrangement
Front
An ordered grouping of elements
Back
Axiom
Front
A statement assumed to be true without proof
Back
Center
Front
The point in the interior of a circle from which all points are equidistant.
Back
Area of a Rectangle
Front
Found by multiplying the length and the width (A = L x W)
Back
Weighted Average
Front
instead of each of the data points contributing equally to the final average, some data points contribute more than others
Back
Bar Chart
Front
A graphical method of showing information by using columns. The length or height of the columns or bars corresponds to the size it represents.
Back
Altitude
Front
A line segment that extends from one vertex or a plane to the opposite side, forming a right angle.
Back
Binomial
Front
A quantity consisting of the sum or difference of two monomials
Back
Base
Front
The bottom-part measurement of a triangle used to calculate the area
Back
Acute Angle
Front
Acute means "sharp". An acute angle is a sharply pointed angle whose size is between 0 and 90 degrees.
Back
360 Degrees
Front
The sum of the central angles in a circle.
Back
Capacity
Front
The maximum amount that a 3-dimensional object can hold.
Back
Associative Property
Front
An operation in which it does not matter where parentheses are placed when three elements are combined. (a + b) + c = a + (b + c)
Back
Additive Inverse
Front
This is the inverse under addition. It is the number which, when added to the given number, gives the identity element for addition.
An example: the inverse of 3 is -3, because 3 + -3 = 0.
For any number a: a + (-a) = 0
Back
Additive Identity
Front
Zero (since 0 + a = a).
Back
Adjacent Angles
Front
Two angles that share the same side or vertex.
Back
Balance
Front
A remaining amount
Back
1 to 1 ratio
Front
A ratio that is equivalent to one.
Back
Area of a Circle
Front
A = (pi)(r squared)
The product of 3.14 times the radius of the circle squared
Back
Area
Front
The number of square units of a surface
Back
Arc
Front
Part of a circle; it is a line, straight or curved, which joins two points.
Back
30-60-90 Triangle
Front
A right triangle with interior angles equal to 30 degrees, 60 degrees, and 90 degrees. The length of each side will follow the ratio 1:2: square root of 3.
Back
Angle
Front
Two rays joined by their endpoints; the amount of "turn" from one ray to another.
Back
Arithmetic Sequence
Front
A sequence in which the difference between any two consecutive terms are the same.
Back
c times
Front
as old as Jim = (c x Jim's age)
Back
Alternate Interior Angles
Front
For two lines cut by a transversal, a pair of nonadjacent angles located between the two lines and on opposite sides of the transversal
Back
Combined Average
Front
Taking the average totals of a group of two or more and adding them together and dividing by the total of members
Back
Bisect
Front
To cut into two equal parts
Back
Algebraic Expression
Front
An expression having at least one variable; they can be added, subtracted, multiplied, and divided.
Back
Base Angle
Front
An acute angle that's opposite the congruent sides
Back
Absolute Value
Front
The distance of a number from the origin (e.g., -5 and 5 have an absolute value of 5).
