Angles/Triangles
A triangle that has two equal sides
Isosceles
The line that goes from the center to the edge of a circle.
Radius
The chances of something happening.
Probability or theoretical probability
What are the three measures of center?
Mean, median, and mode
What kind of decimal "stops" (like 0.75)
Terminating
A triangle that has three equal sides
Equilateral
The line that goes across the circle, through the center.
Diameter
Probability based on the results of an experiment.
Experimental Probability
What are the three measures of variability that we talked about this year?
Range, IQR, and MAD
How much for one
Unit rate
Two angles whose measures add to 180 degrees.
Supplementary angles.
The measurement of the space inside a circle
Area
When the probability of an event is between 0 and 50%
Unlikely
How do you find the median of a data set?
Put all the numbers in order from least to greatest and cross them out until you find the one in the middle.
A letter used to represent an unknown number in an equation or expression
Variable
Two Angles whose measures add to 90 degrees.
Complementary angles
The distance around the outside of a circle
Circumference
When the probability of an event is between 50% and 100%.
Likely
What do we call the distance between the biggest and smallest number in a data set?
Range
The property we use when we take a number outside of parentheses and multiply it by what is inside the parentheses.
Distributive
A triangle has angle measures of 30 degrees, 60 degrees, and 90 degrees. Its side lengths are 3 inches, 4inches, and 5 inches, Give me both names for this triangle.
Right scalene triangle
What do you call half of a circle? (Some times we have the find the area of this when finding the area of a composite figure).
Semi-circle
The list of all possible events in experiment
Outcomes
Which measure of center are we finding when we add all the numbers in a data set and divide by how many there are?
Mean
The distance a number is from 0. (Always positive).
Absolute value
