azimuth 100 degrees altitude 20 degrees
The point on the horizon that is due west has an altitude of zero and an azimuth of 270 degrees.
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.
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.
A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
No. Betelgeuse is a single star.

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.
Recording the location of a star requires a measurement of altitude, azimuth, and time.
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.
If a star's azimuth is 90 degrees, it is located directly east on the horizon. An altitude of 45 degrees means that the star is positioned halfway up in the sky, forming a right angle with the horizon. Therefore, this star would be visible in the eastern sky at an angle that is halfway between the horizon and the zenith.
The variation of the apparent azimuth and altitude of everything we see in the sky is the result of Earth's rotation.
A star with an azimuth of 180 degrees would be due south, and an altitude of 20 degrees would place it 20 degrees above the horizon. So, the star would be in the southern part of the sky, 20 degrees above the horizon.
No, Betelgeuse is a red star.
No. Betelgeuse is a single star.
This is probably about the "horizon coordinate system". Or, it's sometimes called the horizontal coordinate system. The system uses "altitude" and "azimuth" as coordinates. The azimuth is normally measured from due North as zero. So, that's the "three reference points", probably. Altitude is the angular height of a star above the horizon. Azimuth is the angle of a star measured along the horizon, from the pole.
