Interior Angle And Exterior Angle. The diagonals bisect each other. Even though we know that all the exterior angles add up to 360 we can see by just looking that each angle A text and and angle B are.
The diagonals bisect each other. Together the adjacent interior and exterior angles will add to 180 180. Exterior angles of a polygon are the angles at the vertices of the polygon that lie outside the shape.
Even though we know that all the exterior angles add up to 360 we can see by just looking that each angle A text and and angle B are.
I 8 - 2 x 180 i 1080 To find the individual angles of this regular octagon we just divide the sum of interior angles by 8. For our equilateral triangle the exterior angle of any vertex is 120 120. An interior angle is an angle inside a shape. Although you know that sum of the exterior angles is 360 you can only use formula to find a single exterior angle if the polygon is regular.
