  Galaxy triplets are interesting laboratories where we can study the formation
and the evolution of small and large systems of galaxies. This study aims to
investigate signs of interaction between the members of nine isolated galaxy
triplet systems (27 galaxies) selected from the "SDSS-based catalogue of
Isolated Triplets" (SIT) with members brighter than 17.0 ($m_r\le$ 17.0) in the
$r-$band, and mean projected separation between the members of $r_p \leq$ 0.1
Mpc. In this work, we performed a one-dimensional (1D) fitting of the surface
brightness profiles and a two-dimensional (2D) modeling of the sample galaxies.
In the 1D fitting, we examined the far outer part of the light profiles of disk
galaxies (22 galaxies) and categorized them into type I (simple exponential),
type II (down-bending), and type III (up-bending). This fitting results showed
that 55$\%$ of disk galaxies in our sample represent type III i.e are in state
of interaction. In the 2D modeling, we fit smooth axisymmetric profiles to the
27 galaxies and found that 70$\%$ exhibit asymmetric features and signs of
interactions in their residual images. Thus, we conclude that galaxy triplets,
with projected separations ($r_p \leq$ 0.1 Mpc) between their members, are
physically bounded systems that show pronounced signs of interactions.
