There are a number of ways to describe locations or positions. One of these is to describe the direction toward an object in degrees; this is the "azimuth". For objects in the sky, we must also know the angular elevation above the horizon, or "altitude angle". This is usually shortened to "altitude".
By specifying the azimuth angle and altitude angle, we can describe precisely the direction of any object in the sky.
The azimuth and altitude of Sagittarius depend where you are on Earth and the date and time. The altitude can be anything form 0-90, and the azimuth 0-180.
An object seen halfway between the horizon and the zenith has an altitude of 45 degrees.An object seen due east of the observer has an azimuth of 90 degrees.
As of 2021, Betelgeuse has an azimuth of around 225 degrees and an altitude of about 27 degrees when observed from the northern hemisphere. These values will change throughout the night and over the course of the year due to the Earth's rotation and orbit.
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.
The azimuth of the North Celestial Pole is zero ... it's due North. The altitude of the North Celestial Pole is the same as your north latitude. In mid-town Manhattan, that's about 42.6 degrees.

Azimuth = 315° (True) Altitude = 0
The variation of the apparent azimuth and altitude of everything we see in the sky is the result of Earth's rotation.

Yes, the rotation of the Earth affects the azimuth and altitude of celestial objects, as they appear to move across the sky due to the Earth's rotation. The azimuth (horizontal direction) changes as objects rise in the east and set in the west, while the altitude (vertical angle) changes as objects rise higher in the sky and then descend.

The two types of sundials are altitude and azimuth sundials.
Azimuth is the horizontal angular distance measured clockwise from true north, while altitude is the vertical angular distance above the horizon. Together, these coordinates help locate a star's position in the sky.
Azimuth is the angle, typically using true north as zero degrees to an object from viewers location. An altitude (if expressed as an elevation angle from the viewer) provides a line of sight to an object in space. If you were standing at a point and facing true north and there was an airplane flying at 20,000 ft and you knew the elevation angle you could compute the range and have an (X,Y,Z) location for the object.
