Polygons can be regular or irregular in shape. A polygon is a closed 2D shape with at least three sides. A regular polygon is a polygon with all equal sides and angles. An irregular polygon is a ...

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into ...

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into ...

A nonagon has nine sides and a decagon has ten sides. To understand polygons, a good understanding of other angle rules, including triangles and quadrilaterals can be helpful. The word for the name of ...

It may be useful to refer to M1 properties of angles; M1 properties of 2D shapes and M5 Polygons if necessary. The sum of the angles inside any polygon can be found by spitting the polygon into ...

The sum of interior angles in a quadrilateral is 360°. This fact is a more specific example of the equation for calculating the sum of the interior angles of a polygon: \(\text {Sum of interior angles ...

Before reading this guide, it may be helpful to read the guides from Module 1 on the properties of angles and the properties of 2D shapes. The sum of the angles inside any polygon can be found by ...

A polygon is simply a shape with three or more sides and angles. Quadrilaterals are 2D shapes with four sides and angles. There are six special quadrilaterals with different properties. A rectangle ...
