2.  Does drawing a line from the  points help?
3. Will (a,b) be important to finding the general mapping notation?
4. What is mapping notation really?
5.  What quadrant is the point in? 
6. Will it be easier to do this problem algebraically or graphically?

2. Are there multiple image points?
3. Should we just rotate points? Or should we try to construct a line or a circle? Could we use multiple points to construct this circle?
4. Could we make the point we are rotating around be the origin? Like make a new coordinate plane where its the center?

2)Can this be redrawn with it centered at 0,0?
3)Is the line between the image and pre-image straight? 
4)Can the slope of the line between the image and point of rotation be used to solve?

2. Are there other figures one could construct to more accurately map the image on a graph?]]> 2020-10-20 17:05:10 UTC https://padlet.com/triciaphaneuf2/n2bzmyr8gdort7te/wish/845792063 isa_phaneuf https://padlet.com/triciaphaneuf2/n2bzmyr8gdort7te/wish/845797731 1.  when we do the half turn (180 degrees) do we just flip the points?

What does “applied to” mean?
Can we eventually use numbers that aren’t multiples of 90?
Will it be like the vertical/horizontal lines where we had it in terms of the line instead of quadrants?]]> 2020-10-20 17:08:38 UTC https://padlet.com/triciaphaneuf2/n2bzmyr8gdort7te/wish/845808748 imanihernden1 https://padlet.com/triciaphaneuf2/n2bzmyr8gdort7te/wish/846323663 2020-10-20 19:01:56 UTC https://padlet.com/triciaphaneuf2/n2bzmyr8gdort7te/wish/846323663 https://padlet.com/triciaphaneuf2/n2bzmyr8gdort7te/wish/856352590 180 degrees: (x,y)---(2ca - x, 2cb - y)
