    Rotate from specific point so first 1) subtract that point from all other given points. then 2) rotate, then 3) add same point.
    Original points are : (2, -2)(3, -3) (1, -5) Rotate 180 degree from ( -1, -1) So,
    Rule 1) subtract -(-1, -1) from all three numbers. new points will be (3, -1) (4, -2) (2, -4).
    Rule 2) rotate 180 degree so from Q IV to Q II, point will be be the same x, y , but x will become negative (-3, 1) (-4, 2) (-2, 4)
    Rule 3) add +(-1, -1) to all three points so new points (-4, 0) (-5, 1) (-3, 3). Since it says Rotate so do only clock wise. Hope this will help you. Good luck!!! Namo Buddhaya Jai Bheem!!!

    Your method is not completely accurate.
    I was looking at your video, and although your first few steps are correct, you forgot to add one more essential step.
    You were correct about this:
    1) Identifying the center of dilation and plotting it on the graph
    2) Changing the x and y axis so the center of dilation could be (0, 0) aka the origin.
    3) Finding your new coordinates with your "new" x and y axis (You don't have to graph a new x and y axis just to make the center of dilation the origin. A simpler way of doing this is by finding the opposite value for both the x and y coordinate of the center of dilation and adding/subtracting the opposite values to the original shape's coordinates. For example, if your original shape's coordinates were (1,1) (2,2) and (3,3) and your center of dilation was (-1, -1), I would first add the opposite value of the X coordinate of the center of dilation to each X coordinate of the original shape, so it would be (1(+1),1) (2(+1),2) and (3(+1),3). Then, since the opposite value of the Y coordinate of the center of dilation is 1, I would do the same for the y coordinate and add 1 to each y coordinate of the original shape.)
    4) Based on whether the problem wants you to rotate counterclockwise/clockwise and how many degrees the problem wants you to rotate your shape, find the rule and apply it to your shape's coordinates that was added/subtracted by the opposite values of the x and y coordinate of the center of dilation). For example, after completing step three, my new coordinates would be (2, 2) (3, 3) and (4, 4). If the problem said to do a 90° clockwise rotation, since the rule is (x, y) --> (y, -x), I would do
    (2, 2) --> (2, -2)
    (3, 3) --> (3, -3)
    (4, 4) --> (4, -4)
    to find the new coordinates.
    Here are some of the rules:
    90° clockwise/270° counterclockwise rotation: (x, y) --> (y, -x)
    180° clockwise/counterclockwise rotation: (x, y) --> (-x, -y)
    270 clockwise/90° counterclockwise rotation: (x, y) --> (-y, x)
    360° clockwise/counterclockwise rotation: (x, y) --> (x, y)
    Now, you just ended there. However, there is one more important step:
    5) With my new coordinates, (2, -2) (3, -3) and (4, -4), you must add the values of the x and y coordinate of the center of dilation BACK to the new coordinates. For example, since my center of dilation was (-1, -1), I would do this:
    (2(-1), -2(-1)) is (1, -3)
    (3(-1), -3(-1)) is (2, -4)
    (4(-1), -4(-1)) is (3, -5)
    The new coordinates above are the *correct* coordinates for your rotated shape.
    I apologize for this long list. Your answers for some of geometric problems were incorrect. The reason I wrote this was because I kept getting incorrect answers with your steps since you accidentally forgot the final step.
    Thank you for your insightful video, and have a nice day.

    Problem 2 is wrong (your video thumbnail !!). You forgot to add the 1,1 back in. The question doesn't state to RESET the origin to 1,1, thus the origin is still 0,0. This should of been obvious as your video title states "Not the Origin". Correct... 1,1 is NOT the origin, origin is still 0,0, which is where the points B,R,W are derived from (it's asking to rotate around POINT 1,1, not origin 1,1).

    • @MrHelpfulNotHurtful
      @MrHelpfulNotHurtful  3 ปีที่แล้ว

      I propose a challenge. Perform rotation around the point (1,1) using the method of your choice and then tell me the coordinates of your answer. Then we will compare to the answer that I have graphed and we will see if the answers are different.

    • @MrHelpfulNotHurtful
      @MrHelpfulNotHurtful  3 ปีที่แล้ว

      The graph is accurate the way I did it. You would only take the extra step of subtracting the (1,1) at the end if you wanted to list out the coordinates of the vertices of your final answer. Of course you could also get those vertices from the graph. In fact, that’s a way to check your answer. Subtract (1,1) from the green coordinates I had and see if you get the actual coordinates of the final triangle.

      There are no other rotation rules that I know of besides the three covered in this video. 90 degrees clockwise, 90 degrees counterclockwise and 180 degrees.
      If you see 270 degrees clockwise, that’s the same as 90 degrees counterclockwise.
