Abstract
The angle meter and spirit level apparatus can be affixed to a ladder and used to determine the angle at which the ladder is placed. The apparatus is also self-verifying in that it provides a way to know that the apparatus is operating properly. The apparatus also allows for a ladder or other similar device to be used as a carpenter's level or mason's level to determine true horizontal and also to determine the slope from the horizontal.
