100
The vocabulary word for "slides/shifts"
Translation
100
How many degrees exist on one line?
1800
100
What kind of transformation takes Triangle A to Triangle B?
Translation
Example: When I say describe a transformation, you can say Triangle A translated down 2 units and to right 2 units
100
What does congruence mean?
The two shapes are exactly the same, with the same area, same side lengths, same angles, and same orientation.
100
What's 9 + 10?
21
200
The vocabulary word for "turns"
Rotation
200
How many degrees make up one triangle?
1800
200
In order to do a rotation, what three things do we need to know?
Center of rotation, degrees of rotation, which direction (clockwise/counterclockwise)
200
Are these two faces congruent? Explain your reasoning.

You're selling lemonade for $2 per cup. Your supplies cost $10. How many cups do you need to sell to make a $20 profit?
15 cups of lemonade!
($30 revenue - $10 costs = $20 profit)
300
The vocabulary word for "flip/mirror/opposite"
Reflection
300
What is it called when two angles added together make up 1800?
Supplementary angles
300
What kind of rigid transformation is shown here?
Reflection
300
These two triangles are congruent. What is the measurement of side length WU? 
30 m
300
How many times can you subtract 5 from 25?
Only once! After that, you're subtracting from 20, not 25.
400
The vocabulary word for a type of transformation that does not bend, break, shrink, or stretch. The image also has the same side lengths, area, and angles.
Rigid transformation
400
What is it called when two angles make up a 900 angle?
Complimentary angles
400
Are these two triangles an example of a rigid transformation? Explain your reasoning.
400
These two triangles are congruent. What is the measurement of line SQ?
32 in
400
How much does is the watermelon, orange, and banana respectively?
Watermelon = 12
Orange = 8
Banana = 5
500
What is the vocabulary word for two shapes that have the same area, the same angles, and the same orientation?
Congruent
500
What is it called when angles 1 and 2 are the same?
(Hint: Mr. K used this name for something else...)
Vertical angles!
(I accidentally called these type of angles vertical angles when they are called "alternate angles" you don't need to know this specific term for the exam, but you will need to know that these angles are the same!)
500
What would the coordinates (1, 2) become after a 1800 rotation?
(-1, -2)
500
A triangle has interior angle measures of 32°, 37°, and x. What is the value of x?
111o
