you don't know how much this means to me...i was going through a mental breakdown on math...watched over 7 to 8 videos but didn't understand, but you made me understand! I am so grateful i came across your channel, just subbed, please keep making these video, thank you! :)
I truly thank you so much!! My kid came to me with her confusion last night and we ended up with more confusion after watching several videos 😂 but after watching your video, I am confident to teach her tonight 💪
after 3 mental breakdowns.. and about 10 videos that i had no clue what was going on. i found this, i never thought you could do it this way. this made me understand it a lot quicker doing it this way. i have a math test in 2 days.. thank you SO SO much. subscribed. ❤
Yay!!!! I’m so glad I was able to help. Go to my main channel and scroll down to your course. You will find all of my videos in one place organized by Unit. Hopefully there will be many more videos you find helpful. 😊
@@MrHelpfulNotHurtful I have a question, if my coordinates were (-1,-1) on the new axis (aka the new axis using the point as the origin), what do I do using the 90° clockwise rule? Because I tried to change it and it didn't really seem quite right.
@@MrHelpfulNotHurtful thank you, I was a little lost. This applies to all the rotation rules I assume. Thanks again for reaching back so quickly. Does the "-" just mean the opposite of the number for all rules?
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!!!
I can't thank you enough for this! All the other videos were hard to understand but you made it really easy as I'd never thought of doing it this way before. Let's hope I pass this test >:p

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.

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.
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.
Wow. That was an amazing explanation! Sounds like you should make a video. I would definitely watch it. I will have to sit down and contemplate your method to full understand it. Thank you for showing me the right way. 😎
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).
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.

What if it’s 180 degrees and not 90?

can you explain what the other "rules" are for rotations?
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.

Here are some of the rules:

180° clockwise/counterclockwise rotation: (x, y) --> (-x, -y)
270 clockwise/90° counterclockwise rotation: (x, y) --> (-y, x)
