Rigid Motions: Vocab
What is the difference between rotation and reflection?
TURN
(x,y) — (-y,x)
(x,y) — (-x, -y)
(x,y) — (y, -x)
FLIP! over the line of reflection. Lines of symmetry are examples of lines of reflection.
Draw a translation for point G (5,6) following this rule: (x-3, y+5).
Reflect it over the X-axis.
Answer: G': (2, 11) — (2, -11)
What is the mathematical rule for translation?
(x,y) — (x +/- h, y +/- k) where h is the horizontal shift and k is the vertical shift.
You have a missing assignment. Where can you find/ get it?
1. Schoology
2. Your teacher
What is the capital of Colorado?
Denver!
What is the difference between similar and congruent?
Congruent is preserving.
Similar means same shape, but not the same size.
Draw and describe: (x,y) — (x,-y)
Reflection over the x-axis.
I will check the picture :)
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)
You have a test on a subject you struggle in. Name 4 things you can do to feel more confident on that test.
1. Talk to your teacher about help.
2. Study your notes.
3. Create a study group with kids in the class.
4. Quiz yourself.
5. Something else your tutor approves!
True or False: A koala's diet is mainly eucalyptus, but they also eat bugs and other plants to compensate for the low nutrient level in eucalyptus leaves.
FALSE!
They have a very low-nutrient diet, and are one of the least intelligent mammals as a result!
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.
Draw a turtle. Rotate the entire image 270º.
(x,y)—(y, -x)
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.
1. Titling
2. Folders/ binders
3. Color coding
4. Underlining and annotating
5. Something else that your tutor approves :)
What figurehead is the nominal ruler of over 15 different countries?
Queen Elizabeth II
What is: Isometric
Not dilated; the same size.
Does not effect or influence orientation.
Draw an emoji that describes your mood right now. Reflect the entire image across the x axis, then across the y axis
(x,y)—(-x,-y)
Point A (4,5) is rotated 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)
4. Your signature
5. Something else your tutor approves! :)
Why was the Nobel Prize first invented?
Bonus points! Who invented it?
Alfred Nobel invented it after seeing the effect of his newest invention, dynamite. In his will, he allocated all his remaining wealth to the prize as reparations for the violence he introduced to the world.
What is: Dilation
A stretch or shrink of an image
Draw your tutor on a graph. Now, reflect the image over the y-axis and translate it by (x-2, y+5). Rotate the image 90º clockwise.
Where am I now?
Ms. Rawlinson checks!
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 your tutor approves :)
What is the healthiest place on the earth?
SPAIN!
Spain is the healthiest country in the world. Spain is one of the few countries that boasts of a diet based on the Mediterranean Diet. And because of this, Spanish people suffer from fewer diseases compared to the rest of the world.
