I can always change change it to something like this: A square has four equal sides and four right angles. Every square is a rectangle. Learning the relations between different geometric figures is useful. > Old: "A rectangle has four sides and L-shaped corners." > New: "A rectangle has four sides and four right angles." > > This is getting advanced.

It's just a rotated square, and Tux Paint supports rotating. Perhaps it can be replaced by a star or something? -- Karl Ove Hufthammer _______________________________________________ Tuxpaint-dev mailing list [email protected] http://tux4kids.net/mailman/listinfo/tuxpaint-dev
