Pythagorean theorem (a2+b2=c2)
trigonometry functions (sin, cos, or tan)
inverse trigonometry functions (sin -1,cos -1, or tan-1 )
2
When a question asks you to find perimeter and you are given ordered pairs, what formula do you use?
Midpoint Formula
Quadratic Formula
Distance Formula
Addition Rule
3
What determines if two shapes are similar?
the rotation
same size
same angles
same sides
4
How do you know if lines are perpendicular?
same y-interecept
opposite and flipped slope
opposite and flipped y-intercept
same slope
5
What does a dilation do to the slope of a line?
keeps it the same
changes it by the scale factor
6
If you want to make two objects that are similar, but not congruent what type of transformation do you perform?
translation
rotation
reflection
dilation
7
In order to rotate an object onto itself, where do you rotate it?
about one of the vertices
about the center of the object
about the midpoint of one of the sides
about the origin
8

Pythagorean theorem (a2+b2=c2)
trigonometry functions (sin, cos, or tan)
inverse trigonometry functions (sin -1,cos -1, or tan-1 )
9

Quadratic Formula
Midpoint Formula
Distance Formula
Addition Rule
10

add
subtract
divide
multiply
11

trapezoid
square
rectangle
rhombus
12
What does it mean when it says find the possible value?
you can pick any number
there are multiple ways to get your answer
there are multiple correct solutions
there is one solution
13

multiply
divide
add
subtract
14
If trying to find what is left over, what operation do you do?

15
What is the relationship between an arc and an inscribed angle?
the inscribed angle is the same as the arc
the insribed angle is half of the arc
the inscribed angle is double the arc
to find the arc you must subtract the angle from 180
16
What does a dilation do to the y-intercept?
changes it by the scale factor
keeps it the same
17
How do you know if lines are parallel?
same slope
same y-interecept
opposite and flipped slope
opposite and flipped y-intercept
18
What is the relationship between an inscribed angle and a central angle?
to find the inscribed angle you must subtract the central angle from 180
the central angle is double the inscribed angle
the central angle is the same as the inscribed angle
the central angle is half of the inscribed angle
19
If you want to find a missing side and know two shapes are similar, what do you need to do?
guess
make two fractions and cross multiply
subtract the sides
use trigonmetry
20
What is the relationship between an arc and a central angle?
the central angle is the same as the arc
the central angle is half of the arc
to find the arc you must subtract the angle from 180
the central angle is double the arc
21
How do you find midpoint of two points?
add the x's and y's. Then divide by 2
add the x's and then divide by 2. add the y's and then divide by 2
add the x's and then multiply by 2. add the y's and then multiply by 2
add the x's and y's
22
In order to write a formula for a circle, what must you do with the center?
switch the x and y. also change the signs
switch the x and y
keep the signs
change the signs
23
If you are given a triangle with an angle and a side, what do you use to find a different side?
Pythagorean theorem (a2+b2=c2)
inverse trigonometry functions (sin -1,cos -1, or tan-1 )
trigonometry functions (sin, cos, or tan)
