Why did Jesus pray if He is God?

After this manner therefore pray ye: Our Father which art in heaven, Hallowed be Thy name. Matthew 6:9

"Jesus, as part of the Holy Trinity, is indeed God. 

Yet, when He took on human form in the incarnation, He fully

embraced humanity, which included a dependency on communication with the Father.
His prayers exemplify His reliance on the Father and the Holy Spirit. 

By praying, Jesus showed His followers an example of a proper relationship with God, one that is based on communication, submission, and dependence."
