I'm not so sure the definitions are more correct. They are certainly aimed at older people. Old: "A square has four equal sides and L-shaped corners." New: "A square is a rectangle with four equal sides." Now one shape depends on another. I thought of, and had to reject, "rectangular rhombus". If you're going to make one shape depend on another, the "four" should go. I still like the old way better. Old: "A rectangle has four sides and L-shaped corners." New: "A rectangle has four sides and four right angles." This is getting advanced. Classifying angles is a part of geometry, in the 9th or 10th year of school. If it's otherwise in your part of the world, you can translate it as needed. Old: "Oval" New: "An ellipse is a stretched circle." Is it an ellipse? (and, should it be?) All non-trivial ellipses are oval, but not all ovals are ellipses. The side view of an egg is oval, and a rectangle with two semi-circles fitted to the sides is also oval. As for it being a stretched circle, hmmm, that's not a definition I'm comfy with. Old: "A rhombus has four equal sides." New: "A rhombus has four equal sides, and opposite sides are parallel." The first part is enough to define a rhombus. The second part requires geometry. _______________________________________________ Tuxpaint-dev mailing list [email protected] http://tux4kids.net/mailman/listinfo/tuxpaint-dev
