Use this verb dictionary.
For each and every verb, you have to drill the forms in the box at the top:
- steigen, es steigt, es stieg, es ist gestiegen
Also see e.g.
- treten, es tritt, es trat, es hat getreten
from your examples.
Those are infinitive, third person Präsens, third person Präteritum, Perfekt auxiliary and Partizip II. With some practice, you can guess all the other forms of the verb (find them below in that dictionary) from those four.
But you have to know the four forms above for each verb because you cannot guess those. There are only 175 of those “strong” stems but because of the many prefixed variants they make up about half of the verbs in everyday use. So drill them until you got it.
