For example: a 40mm lens will give a 30-degree horizontal angle of view in the Super35 format.

Its almost horizontal angle showed that it opened to a roof at the middle of the building.

We can measure our progress by sighting against it at what seems like a horizontal angle.

This caters for changes in shaft length and horizontal angle.

In addition to the horizontal angle, the key light can be placed high or low producing different effects.

Alternatively, it may sometimes be based on horizontal angle of view.

The theodolite is used to measure horizontal and vertical angles to target points.

They also facilitate vertical and horizontal angles in otherwise straight pipelines.

The builder's level measures neither horizontal nor vertical angles.

Another technique is available for those who possess instruments that will measure horizontal angles.
