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
40 sides
