Would it be by SSS?

anonymous · Answer

why do you think it is SSS ? you know only about two sides of each triangle

anonymous · Answer

you see they have common angle.. it is a good thing to start with

anonymous · Answer

WAIT it would be SAS. Because they share both sides..  TUD is inside SUY, so they share both sides. They don't share the same base, but they do both share U at the top. Would that make it SAS? @Coolsector
