What are the internal and external angles in the building?

Yin angle refers to the concave angle on the wall, also called Yin angle, such as the four corners of the house in the room. Corresponding to it is the external angle, which refers to the angle protruding from the wall.

When making internal corners, you must play ink lines on both sides; When measuring the internal angle, pull the 5m line for inspection (less than 5m line for inspection). The "straightness" of the inner angle should be within 3mm, and the square of the outer angle should be between "0" and "0" (that is, there is no error). You can be anywhere.
