Rigid Motions: Vocab
What is the difference between rotation and reflection?
Rotation rotates the shape around a point
Reflection causes a mirrored image across a line

You have a missing assignment. Name 3 next step options you can take.
1. Email your teacher to help you make a plan.

5. Another answer that Ms. Herde approves of :)
What is the animal with the longest tongue?
Giraffe
What is the difference between similar and congruent?
Congruent is preserving. (equal)
Similar means same shape, but not the same size. (proportional)
What is the algebraic notation for 3 units up, and 4 units to the right?
(x+4, y+3)
What is the rule for Reflection?
(there are 4 cases)
Over the x-axis: (x,y) — (x,-y)
Over the y-axis: (x,y) — (-x,y)
Over the line y=x: (x,y) — (y,x)
Through the origin: (x,y) — (-x,-y)
How do you check your grades?
Powerschool; schoology?
What is Mr. Rob's first name?
Seth!
What does preserving mean?
Angle preserving? Distance preserving?
Each angle measure is the same pre and post transformation.
Corresponding side lengths remain equal pre and post.
What is the notation for 5 down and 2 to the left?
T -2, -5
What is the rule for Rotation?
90º and 270º: (x,y) — (-y,x)
180º: (x,y) — (-x, -y)
270º and 90º: (x,y) — (y, -x)
Name 3 organization strategies for your notes.
2. Folders/ binders
3. Color coding
4. Underlining and annotating
5. Something else that Ms. Herde approves :)
What color is the rarest m&m?

What is a vector?
An arrow indicating direction of translation
What is the description for this notation? T -2, 5
Up 5 units, to the left 2 units
Below is the triangle FUN. ;)
F: (-4, 4)
U: (3, 1)
N: (-1, 2)
Write the coordinates for F', U', N' after a reflection over the X-axis.
F': (4, -4)
U': (-3, -1)
N': (1, -2)
How can you interact with your notes to successfully and efficiently study? Name 5 tricks.
1. Annotating and highlighting
2. Flashcards
3. Quizlet/ kahoot
4. Reading them again and rewriting them in a different way
5. Making a review sheet with them (condensing them); Writing summaries
6. Making connections to things you already know. Create questions that relate to the information outside of the class
7. Act them out!
8. Teach them to someone else! (Study group???) :)
9. Something else Ms. Herde approves :)
What are all the skittle flavors?
What is: Isometric
Not dilated; the same size.
Does not effect or influence orientation.
Point J is (6, 9). What is J' when T -1, 9
J' (5, 0)
Point A (4,5) is rotated over the 180º. Write the coordinates of A'.
Answer: (-4,-5)
What are 3 staple things to put in a professional email?
1. A thoughtful and respectful greeting
2. Your question and or concern
3. A date and time available to meet (if applicable)
