Terms in this set (45)
absolute value
Distance from zero on a number line
acute angle
an angle whose measure is less than 90
circumference
the distance around a circle
adjacent angles
two angles that share a common side and have the same vertex
angle
a figure formed by two rays with the same endpoint
angle of rotation
the number of degrees a figure rotates
area
The amount of surface covered by a figure. Area is measured in square units such as square feet..
complementary angles
Two angles whose measures have a sum of 90
congruent
Having the same size and shape.
congruent angles
angles that have the same measure
congruent figures
figures that have EXACTLY the same size and shape
congruent sides
sides that have the same length
constant term
a term that has a number but no variable
ex. 2x + 8 (8 is the constant term)
Cross Products Property
the cross products of a proportion are equal
denominator
the number below the fraction bar in a fraction
In the fraction 2/5 the denominator is 5.
diameter
the distance across the center of a circle
mean
the sum of the values in a data set divided by the number of data values
numerator
the number above the fraction bar in a fraction -
In the fraction 2/5, the numerator is 2.
median
For a data set with an odd number of ordered values, the median is the middle data value. For a data set with an even number of ordered values, the median is the mean of the two middle values.
range
the difference between the greatest value and the least value of a data set - the range describes how spread out the data are
difference
answer to a subtraction problem
sum
answer to an addition problem
product
answer to a multiplication problem
quotient
the answer to a division problem
negative number
a number less than 0
obtuse angle
an angle whose measure is greater than 90 and less than 180
order of operations
the order in which to perform operations when evaluating expressions with more than one operation - when evaluating 5 + 2 x 3, you multiply first... Please Excuse My Dear Aunt Sally (parenthesis, exponents, multiplication, division, addition, subtraction)
ordered pair
a pair of numbers (x,y) used to locate a point in a coordinate plane
perimeter
the distance around a figure
proportion
an equation stating that two ratios are equivalent 3/4 = 12/16
radius
the distance from the center of a circle to any point on the circle
factor
when whole numbers other than zero are multiplied together, each number is a factor of the product 2 x 3 x 4 = 24 (so 2, 3, and 4 are factors)
ray
a part of a line that has one endpoint and extends without end in one direction
right angle
an angle whose measure is 90
similar figures
figures that have the same shape but not necessarily the same size
slope
a ratio of the change in y to the change in x between any two points on a line (it is the measure of steepness of a line)
supplementary angles
two angles whose measures have a sum of 180
surface area
the sum of the areas of all faces of an object
unit rate
a rate with a denominator of 1 (the speed limit is 65 miles per 1 hour)
variable
a symbol, usually a letter, that represents one or more numbers (x is the variable in 2x + 1)
mixed number
a number consisting of an integer and a proper fraction
digit
any of the numerals 0 - 9
octagon
8 sided polygon
hexagon
6 sided polygon
quadrant
