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 ...

Achieving perfect 30, 45, and 60-degree angles doesn’t have to be difficult – it's all about understanding the geometry ...

A regular polygon is a polygon with all equal sides and angles. An irregular polygon is a polygon where this is not the case. Knowing the difference between regular and irregular polygons can help ...

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 ...

The sum of the angles inside any polygon can be found by spitting the polygon into triangles. Consider any triangle. The sum of the angles is known to be 180° A quadrilateral can be split into ...

The sum of the angles inside any polygon can be found by splitting the polygon into triangles. The number of triangles that a polygon can be divided into is always two less than its number of sides.

Where the straight sides of the polygon meet, an angle is created. Angles are measured in degrees (°). The internal angles of a triangle add up the 180° and the internal angles of a ...
