Definition
Shape
A shape is a geometric figure identified by mathematical properties, not by colour or position.

What it means
Look for the properties that stay true. A triangle is still a triangle when it is turned, made larger, or coloured differently. Changing a defining property, such as the number of sides, can change the shape’s name.
Remember it
Turn it, move it, resize it—the defining properties decide the shape.
Example
Maya rotates a scalene triangle so one side points straight up. It still has three straight sides and three vertices, so it is still a triangle.
Watch for
This card owns the geometric sense of “shape,” not phrases such as the shape of a data distribution or being in good shape.
Common mix-up
Size, colour, and orientation are usually non-defining; sides, angles, curves, faces, edges, and vertices can be defining.
Exact meaning
In geometry, a shape is a two-dimensional figure or three-dimensional form described by properties such as sides, curves, angles, faces, edges, vertices, or dimensions.
