  My first thought was, thats not a square, its a rectangle - but the square was angled.

  I drew a circle with 3/4 at the centre and radius to 1/5. Subsequently, the only coordinate that matched the answers was 2/2. Thank you for the Easter treat.

  I am surprised to note that this is the first time I can recall being exposed to vectors in such a manner. <br>Thank you, Susanne! &nbsp;Way cool (as always).

  Key is simply to note that the square has to be rotated.

  Hello, my lovely Susanne. &nbsp;You tried to trick us with that thumbnail. &nbsp;I looked at that and knew it couldn&apos;t be (5,5) like the thumbnail would suggest because it wouldn&apos;t be a square, but a rectangle. &nbsp;It never occurred to me the square would be rotated on the graph. &nbsp;Very well done video.

  My first thought was to draw a circle with radius AM. No matter how the square is rotated, which it had to be with the non equal X and Y distances from centre point, the corners would still be on the perimeter of the circle. Draw those points and see if any of them fall on the circle.<br><br>Works great for this simple case, but love the vector explanation for the more complicated coordinates, or if they are trying to trick you by more than one coordinate in the answers being on the circle

  I thought 1,5 was wrong because I imagined an horizontal square, I didn&apos;t think of it as rotated 🙂

  Your teaching style is so excellent that even a most complex problems are easy to understand.moreover, your smiling face creates such positive vibration. Truly,you are an exceptionally a good teacher. With regds.

  I enjoyed your thorough, formal, vector-based approach. &nbsp;I drew the graph and then the four points by counting the x and y offsets originating from the centre point. &nbsp;My first attempt formed a rectangle and not a square. &nbsp;I realized the square must be slightly rotated. &nbsp;I swapped the x and y &quot;increments&quot; to form the rotated square. Thanks for the video!
