True or False: Angle 1 and Angle 4 are congruent.
True. They are congruent because they are vertical angles.

How does Triangle ABC Transform to Triangle A'B'C'?
There is a translation 9 units to the left and 9 units down.
100
What are the two types of dilations?
Enlargement and Reduction.

Leah says the mode is 5. Is she correct? Why or why not?
No, the mode is 35.
200
True or false: The angle measurements for y and 5x are congruent because they are supplementary angles.
False
200
What type of transformation has happened?
A rotation 270 degrees counterclockwise, or a rotation of 90 degrees clockwise.
200
If a scale factor is less than 1, what type of dilation will happen?
There will be a reduction.
200
What does biased mean?
Unfairly prejudiced for or against someone or something.
200
What is the best estimate for the center of this box plot?
Anywhere from 100-150. Probably a little closer to 150.
300
Which three angles have the same measurement as angle 1?
Angle 4, Angle 5, and Angle 8 have the same measurement as Angle 1.
300
What are the 4 types of transformations and how do they change the shape?
Translation = Slide
Reflection = Flip
Rotation = Turn
Dilation = Grow or Shrink
300
What is the scale factor of this dilation?
The scale factor is 2.
300
What is another word for mean?
Average
300
Who has a higher center height? Why?
Boys. Their center height is 62, girls only have a center height of 60.
400
What are the measurements for angle 2, angle 7, and angle 8?
angle 2 = 127 degrees
angle 7 = 127 degrees
angle 8 = 53 degrees
400
What two transformations are happening, include, translation instructions, line of reflection or center of rotation if needed?
There is a reflection over the y-axis and then a reflection over the x-axis.

One of these classes has a 3 certified geniuses in it. Which class most likely has this student?
2nd Period. The scores are generally better.

Angle y and 2(x+6) are corresponding angles. Angle y and 5x are supplementary. If the measurement for angle y equals 60 degrees, solve for x.
x = 24
500
Given this transformation, will the two shapes be congruent? Why or why not?
No, they will not be congruent because the dilation will change the size.
500
What is the scale factor going from quadrilateral ABCD to quadrilateral A'B'C'D'?
The scale factor is 1/2.

This box plot shows the cost of speeding tickets in 2 states. Julia got a $90 speeding ticket. Which state did she most likely get this ticket in? Why?
State B. The costs are generally higher. They have a mean of 80. Most of the data is between 70 and 100 in State B.
