The number of triangles that a polygon can be divided into is always two less than its number of sides. Consider any triangle. The sum of the angles is known to be 180º. A quadrilateral can be ...

Polygons are 2D shapes that have straight sides. Regular polygons have sides and angles that are all the same size. Let's recap what a polygon is with this quick video. How would you work out the ...

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 ...

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 ...

Interior angles in a triangle add up to 180˚. Triangles close triangleA polygon with three straight sides. have three sides, therefore they have three angles. Interior angles in a triangle sum to ...

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.

See you later. Urgh, uh hello. It’s the irregular polygons. This bunch have sides of different lengths and different angles. JavaScript is required to view this activity.

Polygons can be regular or irregular. If all the straight sides of a shape are the same length and interior angles are the same size, then it is a regular polygon. If the length of the sides are ...
