When making an offset in conduit if the spacing between marks is double the offset depth you kniow that the offset angle is?

When the spacing between marks is double the offset depth in conduit, it indicates that the offset angle is 30 degrees. This relationship arises from the geometry of right triangles, where the tangent of the angle is equal to the opposite side (offset depth) divided by the adjacent side (spacing between marks). Therefore, for an offset depth that results in double the spacing, the angle formed is 30 degrees.
