First angle and third angle are two different methods of representing the orientation of an object in 3D space.

First angle projection is commonly used in Europe and Asia, where the object is placed in the first quadrant of the coordinate system.
Third angle projection is commonly used in North America, where the object is placed in the third quadrant of the coordinate system.
First angle projection symbolizes the object as if it is in front of the viewing plane, while third angle projection symbolizes the object as if it is behind the viewing plane.
