1
If you are given a triangle with an angle and a side, what do you use to find a different side?
inverse trigonometry functions (sin -1,cos -1, or tan-1 )
trigonometry functions (sin, cos, or tan)
Pythagorean theorem (a2+b2=c2)
2
What is the relationship between an arc and an inscribed angle?
the inscribed angle is double the arc
the insribed angle is half of the arc
the inscribed angle is the same as the arc
to find the arc you must subtract the angle from 180
3
How do you know if lines are parallel?
opposite and flipped slope
same y-interecept
opposite and flipped y-intercept
same slope
4
What is the relationship between an arc and a central angle?
to find the arc you must subtract the angle from 180
the central angle is double the arc
the central angle is the same as the arc
the central angle is half of the arc
5
In order to write a formula for a circle, what must you do with the center?
keep the signs
switch the x and y
switch the x and y. also change the signs
change the signs
6
What does a dilation do to the slope of a line?
keeps it the same
changes it by the scale factor
7
You have P(A and B) and P(A). How do you find P(B)?
multiply
divide
subtract
add
8
If trying to find what is left over, what operation do you do?
divide
subtract
multiply
add
9
If you are given a triangle with a two sides, what do you use to find the other side?
Pythagorean theorem (a2+b2=c2)
trigonometry functions (sin, cos, or tan)
inverse trigonometry functions (sin -1,cos -1, or tan-1 )
10
If you want to find a missing side and know two shapes are similar, what do you need to do?
subtract the sides
guess
make two fractions and cross multiply
use trigonmetry
11
When a question asks you to find perimeter and you are given ordered pairs, what formula do you use?
Addition Rule
Midpoint Formula
Quadratic Formula
Distance Formula
12
In order to rotate an object onto itself, where do you rotate it?
about one of the vertices
about the midpoint of one of the sides
about the center of the object
about the origin
13
What reason do you
end
with for almost all proofs with parallel lines and a transversal?
corresponding angles are congruent
reflexive property
transitive property
vertical angles are congruent
14
If you want to make two objects that are similar, but not congruent what type of transformation do you perform?
dilation
rotation
translation
reflection
15
What determines if two shapes are similar?
same sides
the rotation
same angles
same size
16
What is the relationship between an inscribed angle and a central angle?
the central angle is half of the inscribed angle
the central angle is the same as the inscribed angle
to find the inscribed angle you must subtract the central angle from 180
the central angle is double the inscribed angle
17
How do you know if lines are perpendicular?
opposite and flipped slope
same slope
same y-interecept
opposite and flipped y-intercept
18
