Interior Angle And Exterior Angle. The opposite sides are parallel. The interior of together with the angle itself is called the angular region AOB.
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. To find the exterior angle we simply need to take 135 away from 180. An interior angle is an angle inside a shape.
The part of the plane which is outside the arms of an angle produced indefinitely is called the exterior of the angle.
The diagonals bisect each other. Consecutive interior angles or co-interior angles angle 2 and angle 5 angle 3 and angle 8. Alternate exterior angles angle 1 and angle 7 angle 4 and angle 6. Interior and Exterior of an angle Example 1.
