      It took me up until reading your comment to get this one. “Is it that the scaling transformation only scaled the y-axis?? Oh…”

        I teach these basic transformations as part of my middle school math classes, and I was completely loss as to why they didn’t include a reflection, but then I realized a reflection wouldn’t be that interesting because it could be indistinguishable from a translation.

          I was at a loss too as to where they source the “most common” when skewing is also extremely common

            Scaling, in general, is the least common middle school transformation covered by state curriculum as far as depth of knowledge is concerned, at least where I’ve taught. Students just aren’t ready at that age to calculate something as sophisticated as the scale factor contributing to an object’s loss of size.

              I think the students are ready and quite capable of such sophistication. They’re just too distracted with sharing memes.

                (Oh, I know, my middle schoolers do alright as long as our figures are two-dimensional, and my high school geometry students do very well; I just wanted to say the magic, fun, wink wink word again. 🙂)

    I had to look at this twice to get it. I must be losing my touch.

    Ok … I didn’t know this meme (too old and/or out of the loop I suppose) … so out of annoyance I looked it up …

    … and yea … as far as trolling is concerned gotta pay the game here … not sure it was worth 15 mins of my life but … kudos I guess

      Only the transformations one is correct. All the other ones seemingly also preform a translation, and even if they might be correct if you take the orgin to be slightly outside of the shape but that’s bad for educational purposes. Also this one makes the translation transformation look like the identity transformation.

      This last one might just be me, but shouldn’t shearing be included here?

    The second is not really scaled, and the second and forth have translation. Usually that wouldn’t be a problem for demonstrative proposed, if translation wouldn’t be shown explicitly. Can be fixed by introducing a canvas of the before/after picture

      The second is scaled in one axis, and had translation otherwise it would be hard to understand. And the rotation can be achieved by moving the origin of rotation.

    Scaling looks like scaling+translation? And rotation looks like either rotation+translation, or scaling+translation?
