It doesn't show, just when they meet again he suddenly has it
If he can go super sayan 1, 2, and 3 of course he can do it! Besides vegeta did it, so if vegeta can do it, so can goku cause he is stronger!
In the beginning frieza actually killed vegeta but towards the middle of the story vegeta goes super sayan so he would defeat frieza

He becomes a super saiyan a few episodes after planet namek was destroyed
