a comparison of two numbers by division
A ratio that compares two quantities measured in different units
two equal ratios
a ratio that compares a number to 100
a closed plane figure with many straight sides
a three-sided polygon
a triangle having two equal sides
a triangle having three sides of different lengths
a triangle having all sides congruent
an angle that is less than 90 degrees
an angle that measures 90 degrees
between 90 and 180 degrees
a four-sided polygon
A quadrilateral with two pairs of parallel sides
a quadrilateral with two parallel sides
a plane figure with four equal straight sides and four right angles.
a parallelogram with four right angles
a parallelogram with 4 congruent sides
two angles whose sides form two pairs of opposite rays
sum of angles that equals 90 degrees
sum of angles that equals 180 degrees
side by side lines that have the same distance continuously between them
2 lines intersecting to form right angles
identical in form; coinciding exactly when
same shape, but different size
the point of intersection of coordinate axes (0,0)
The four regions of a coordinate plane that are separated by the axes.
a graph that forms a straight line
a graph that does not form a straight line, it may curve
a ratio that describes the steepness of a line
a diagram used to show the total number of possible outcomes
the set of all possible outcomes
Probability based on comparing the number of possible favorable outcomes to the number of total possible outcomes
Probability based on data from repeating an event (doing an experiment)
probability that deals with 2 or more things
The outcome of one event does not affect the outcome of the second event
a group of symbols that make a mathematical statement - NO EQUAL SIGN
a mathematical statement that two expressions are equal- ALWAYS AN EQUAL SIGN
A number multiplied by a variable in an algebraic expression. ex. 4x+2, what is 4?
a symbol (like x or y) that is used in a mathematical expression used to represent a variable quantity
a mathematical notation indicating the number of times a quantity is multiplied by itself
a number that is added to another number
In multiplication or addition, the order of two numbers may be switched around and the answer is the same. Ex: a+b = b+a.
Changing the grouping of numbers will NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication
adding or multiplying by these numbers does not change the answer
The sum of a number and its opposite is 0
A cross product of two fractions is the product of the numerator of one fraction with the denominator of the other fraction.
a symbolic expression of the fact that two quantities are equal; an equation.
