I can find the interior angle of any regular polygon or deduce the interior angle of an irregular polygon.
Show transcript
Any polygon can be split into triangles.
Using these triangles you can demonstrate the rule for the interior angle sum of a polygon.
A missing interior angle in any polygon can be found.
The number of sides in a regular polygon can be determined from the size of the interior angle.
The sum of the interior angles is the same, regardless of whether the polygon is regular.
