median
Middle Number
odd number
Odd numbers can NOT be divided evenly into groups of two
laws of exponents
Rules that describe relationships between exponents for certain operations.
percent
A ratio that compares a number to 100
mode
Most frequently occurring number
properties of a 30-60-90 triangle
integer
the natural numbers, their opposites, and zero
remainder
Amount left over after dividing a number
negative exponent
an exponent less than zero which causes the base and its exponent to move positions in a fraction
formula for the area of a CIRCLE
A=πr²
parallel lines
lines in the same plane that never intersect
prime number
A whole number that has exactly two factors, 1 and itself.
special formula for the area of a triangle
a= 1/2 bh
exterior angle of a triangle
An angle that forms a linear pair with an angle of the triangle
exponent
A mathematical notation indicating the number of times a quantity is multiplied by itself.
ratio
A comparison of two quantities by division (X/Y or X:Y-- numerator associate with word "to" and denominator "of"
straight angle
An angle that is 180 degrees
alternate interior angles
Angles that lie within a pair of lines and on opposite side of a transversal.
average
the total sum of numbers ÷ the amount of numbers
properties of 1
Multiplying a number by 1 gives it that number
measures of the 3 angles in a triangle
should add up to 180
how do you find a percent of a number?
convert percent to a decimal and then multiply times the value
properties of 0
integer, not negative, not positive, even number
multiple of an integer
the product of that integer and another integer
weight averaged
total weight ÷ amount of people weighed
how do you find the distance between 2 points?
c² = a² + b²
counting principal
uses multiplication to find the number of possible ways two of more events can occur
even number
A whole number divisible by 2
measures of the 2 acute angles in a right triangle
should add up to 90
directly proportional
if y is directly proportional to x, then y = kx
difference
subtraction
quotient
division
properties of a 45-45-90 triangle
same side interior angles
two interior angles on the same side of the transversal
Pythagorean theorem
a²+b²=c²
distributive property
a property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac
how do you solve distance problems
D= √(x₁-x₂)²+(y₁+y₂)²
divisor
A number by which another number is divided.
properties of square roots
multiplication of the roots
product
multiply
similar triangles (and their properties)
Similar triangles have the same shape: corresponding angles are equal and corresponding sides are proportional
fractional exponent
The numerator is the power of the base, the denominator is the type of root
proportion
A statement of equality of two or more ratios.
triangle inequality theorem
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
alternate exterior angles
Angles that lay outside the parallel lines and are on opposite sides of the transversal; They are congruent.
corresponding angles
Angles formed by a transversal cutting through 2 or more lines that are in the same relative position.
sum
add
if the product of two or more numbers is 0, what do you know about the numbers?
one of the numbers is 0
factor
a number or expression that is multiplied by another number or expression to get a product
inversely proportional
if y is indirectly proportional to x, then y = k/x
