# 1 Shapes

## 1.1 Polygons

A polygon is simply a general term for a shape with straight sides.

### Activity 1: Identifying polygons

Which of the following shapes are polygons?

Figure 1 Six shapes

Shapes (a), (c), (d) and (e) are polygons. Shapes (b) and (f) are not polygons because they have curved sides.

A regular polygon is a shape with sides that are the same length and angles that are all the same size.

A polygon with six sides is a hexagon. The shapes in Figure 2 are both hexagons, but only one is a regular hexagon.
