how to identify few constellations using orion

Now once you have learnt how to identify Orion, you can know use the stars of Orion to identify other stars and constellations.(One thing that you need to know is that whenever i mention an imaginary line it means a straight line in 2-D.But when you look at the stars because these stars are surrounded spherically these lines would not be straight, they would be slightly curved and so if you make a straight line joining two stars and are unable to find the third star,then look for the star which is closest to the line.) Now lets start with the top two stars of the Orion constellation Betelgeuse and Bellatrix. If you join these two stars  Bellatrix and Betelgeuse and extend the line then you must reach a star which is relatively small and less bright.This star is known as Procyon and there should be an extremely faint star near Procyon.These two stars form the Canis Minor constellation.By extending the belt of Orion in the direction of Alnitak we can reach towards the brightest star in the winter constellation which is know as Sirius.It belongs to the Canis Major constellation.Now if the same line is extended towards Mintaka we'll find a hyper giant star that is reddish in color.This star is known as Aldebaran and it belongs to the Taurus constellation.Now if we join Rigel and Betelgeuse and extend the line further we'll find Castor and the star right next to Castor which is known as Pollux.These two stars belong to the Gemini constellation.If you are viewing Orion through a telescope then you can spot M42 which is also know as the Orion nebula between the Orion belt,Rigel and Saiph.Also if you search in the Taurus constellation you might find M45 which is a cluster of stars.The three stars Betelgeuse,Sirius and Procyon are also know as the winter triangle
