How does Angelou capture triumph in "Still I Rise?"

The confidence that the speaker asserts in the face of adversity communicates triumph in "Still I Rise."

The speaker in "Still I Rise" refuses to acquiesce to anything that tries to keep her subservient.  She is confident she will persevere through these negative elements until she achieves victory.  These realities include being "trod" in the dirt, judged through "twisted lies," and intense "hatefulness."  

The refrain of "Still I rise" conveys triumph by meeting this negativity with resolute strength.   She is going to outlast the forces and people that wish to keep her down. She will meet their challenges with an internal confidence, a resolve that will inevitably fuel her triumph.  It is a confidence that holds "hopes springing high."  The closing of the poem enhances this triumph. When Angelou writes she is "Bringing the gifts that my ancestors gave," it is clear she believes that she is too proud to fail.  She is "the dream and hope of the slave."  She draws confidence from the suffering of those who preceded her.  Their sacrifice fuels her desire for success.  She is confident that she will take that pain and transform it into victory.  Such intensity underscores the triumph so important to the poem.
