Finding Sagittarius and Betelgeuse:

To find Sagittarius, find Scorpio and look to the left. You should see brighter stars. That’s the constellation. It is a picture of a centaur, which is half man and half horse, shooting a bow and arrow.

Betelgeuse isn’t a constellation. It’s a star. It’s part of the constellation Orion. It’s bright and large. It’s in the upper left corner. It has a reddish color. See if you can distinguish its color compared to other stars you see.
