Fascinating Fact:

Polygon A 2D shape with only straight sides. Triangles, rectangles, and pentagons are polygons.

In KS1 Maths, pupils build a shapes vocabulary so they can describe and compare 2D shapes. They learn to talk about sides and vertices and to recognise when a shape is a polygon.

Key Terms

Polygon: A 2D shape made only of straight sides joined in a loop.
Side: A straight line on the edge of a 2D shape.
Vertex (corner): The point where two sides meet. More than one is vertices.

Practise now: open the Shapes Vocabulary game and test your words for polygons, sides and vertices.

Frequently Asked Questions (Click to see answers)

What is a polygon for KS1?

A polygon is a flat (2D) shape with only straight sides, such as a triangle, rectangle or pentagon. Circles are not polygons because their edges are curved.

How do I count sides and vertices on shapes?

Trace the outline and count each straight side. Then count each corner where two sides meet. For a square you get four sides and four vertices.

Is a circle a polygon?

No. A circle has one curved edge and no vertices, so it is not a polygon. Polygons must have straight sides and corners.
