Save guides, add subjects and pick up where you left off with your BBC account. Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular ...

Learn more about how angles in an 𝒏-sided polygon add to 180° × (𝒏 – 2) with this BBC Bitesize Maths article. For students between the ages of 11 and 14.

A similar argument will show that after the hexagon—whose 120-degree angles neatly fill 360 degrees—no other regular polygon will work: The angles at each vertex simply won’t add up to 360 ...

A similar argument will show that after the hexagon — whose 120-degree angles neatly fill 360 degrees — no other regular polygon will work: The angles at each vertex simply won’t add up to 360 as ...

The simplest tilings are made of identical polygons with sides of equal length and angles of equal measure joined full edge to full edge. But although there are infinitely many of these “regular” ...

For example, a regular hexagon is used in the pattern of a honeycomb, the nesting structure of the honeybee. ... no such polygons tessellate unless they have an angle greater than 180 degrees.

Regular hexagons work, too, but not a regular pentagon. The problem with a regular pentagon (all sides the same length and all interior angles the same) is that the interior angle at any vertex is ...
