An interior angle of a 2-dimensional plane shape is an angle on its perimeter that is facing the enclosed area of the shape.An interior angle of a 2-dimensional plane shape is an angle on its perimeter that is facing the enclosed area of the shape.An interior angle of a 2-dimensional plane shape is an angle on its perimeter that is facing the enclosed area of the shape.An interior angle of a 2-dimensional plane shape is an angle on its perimeter that is facing the enclosed area of the shape.
It is the angle that is inside the shape.
An interior angle is the inside angle of a shape e.g quadrilateral, square
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape

It is the angle that is inside the shape.
An interior angle is the inside angle of a shape e.g quadrilateral, square
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
It has (8820+360)/180 = 51 sides
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
Extend any straight side of a shape. The angle made by that side with the adjacent side of the shape is an exterior angle. Its value is 180 degrees less the interior angle.
