I was recently at a conference where we had an exercise with pieces of paper cut in shapes. One of my table mates insisted that only the ones like squares, rectangles, and circles were "geometric." The others, she said, were just shapes. I sure thought any shape was geometric, but then I wonder if she is right. Here is what the online dictionary definition is: "resembling or employing the simple rectilinear or curvilinear lines or figures used in geometry."
only the ones like squares, rectangles, and circles were "geometric."
And triangles, and pentagons, and plenty of other polygons. By adding triangles to a central polygon you can also form stars, and there are plenty of other shapes that can be formed. I can understand what she meant, though I can't agree with such a restricted definition.
