Two Dimensional Polygons

A polygon is:

• An open shape with the same sides and angles

• Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up).

• A 3d shape that is not joined by lines.

The figure can be classified as –

• a parallelogram but not a rectangle
