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 ...

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 ...

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 ...

Polygons are two dimensional shapes with straight sides. They can be described by the number of sides they have and whether the shape is regular or irregular. Where the straight sides of the polygon ...

A scalene triangle has 3 sides of different lengths and 3 unequal angles. An isosceles triangle has 2 sides of equal length. The dashes on the lines show they are equal in length. The angles at the ...
