Answer 1

A shape with only two dimensions (such as width and height) and no thickness. Squares, Circles, Triangles, etc are two dimensional objects. Also known as "2D". See: Three-Dimensional.

A "Geometry Net" is a flattened out three dimensional solid (a three dimensional shape) -- like a cube, a prism or a pyramid. When you cut out the "net", fold it and glue it together you can see what the three dimensional shape looks like.
