It is the angle that is inside the shape.
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape

Interior angle
It is the angle that is inside the shape.
For any quadrilateral it is always 360 degrees. Trigons(triangles) = 180 Tetragons = 360 Pentagon = 540 Hexagons = 720 Heptagons = 900 Octagons = 1080 Nonagons = 1260 Decagons = 1440 NB For each extra side add 180.
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
It has (8820+360)/180 = 51 sides
To work out the interior angle use this formula(n - 2)*180/nwhere n is the number of sidesso for an 18 sided shape it would be(18-2)*180/18 = 160.
Each interior angle of a regular 24 sided polygon is 165 degrees
If it is a regular 8 sided octagon then each interior angle is 135 degrees
