What are vertical angles?
angles across from each other in an X
How many degrees do angles that are next to each other in a line add up to?
180 degrees
Are vertical angles complementary (90), supplementary (180), or equal?
equal
What operation should you use when you see parenthesis
[e.g. y= 3(4x + 1)] ?
parenthesis mean multiplication
What operation should you use when you see the line in a fraction? ( 3 / x)
The line in a fraction means divide. So, 3/x means “3 divided by x”.
What does the word congruent mean?

What kind of circle is used in an inequality to represent “greater than or equal to” and “less than or equal to”? (open or closed circle?)
closed
How do you find an average of something?
“Averaging” means to add up all the numbers and divide by how many numbers there are.
In the equation of a line y=mx+b, what number is found in the “m” spot? (What does the “m” represent”)
The “m” is the slope
In the equation of a line y=mx+b, what number is found in the “b” spot? (What does the “b” represent”)
The “b” is the y-intercept
What is a y-intercept?
A y-intercept is the point where a line crosses the y axis.
How many degrees are in a circle?
360 degrees
How many degrees do the angles in a triangle add up to?
180 degrees
What is the diameter of a circle?
A line that goes all the way through a circle (through the middle)
