- viajar(to travel) → viajado(traveled) 
- viver(to live) → vivido(lived) 
There are also some verbs with irregular past participles, such as escrever(to write) → escrito(written). If you need a quick refresher about past participle verbs in Brazilian Portuguese, check this Brazilian Portuguese past participle reference sheet.
