6 Tri - Physical binary star, whose companion of 7 mag. can be distinguished from the primary star of 5 mag. using a small telescope.

R Trianguli - The variable star of Mira Ceti type with a magnitude fluctuation from 5.7 to 12.6 with a period of 267 days.

ε Tri - unequal double star with a brighter pale blue component (5.4 magnitude) and a much fainter white companion (11.4 magnitude). They can be easily resolved (3.9 arcseconds) with a 200mm telescope.

ι Tri - A binary star with components of brightness 5.3mag and 6.9mag is separated by 3.9". To resolve the yellow and blue stars, we need an 80mm telescope.
