When two lines meet it is usual to refer to the angle between them by the smaller of the two angles they form. Both angles always add up to 360..... the usual way of defining an angle is to name the lines that form it, and to do so in a clockwise manner. Looking at the four main compass points (N, E, S and W) and naming the centre as C..... the angle between North and East would be referred to as NCE..... this angle measures 90 degrees. The exterior angle is ECN and is 270 degrees. Usually exterior angles are only referred to when the interior angle is part of an enclosed figure, such as a triangle or other polygon.
