The segment-segment angle distribution gives us information about the orientation of the segments relative to each other which can be calculated based on the angle between two successive segments $\theta =  \langle \arccos \left( {\bf u}_{i}(t)\cdot {\bf u}_{i+1}(t)/\left|{\bf u}_{i}(t) \right| \left|{\bf u}_{i+1}(t) \right| \right)\rangle_{i,t} $. The results are presented in Fig. \[fig:bond-ang-dist\].

![(color online) The segment-segment angle frequency distribution. The plots represent distribution of the angle between two successive segments for each chain. The radius of the confining sphere in each plot is (a) $49 \, \sigma$ and (b) $14 \, \sigma$ which shows a drastic change in the angle distribution of longer segments where they are mainly parallel to each other, the first peak, or forming part of an imaginary polygon.[]{data-label="fig:bond-ang-dist"}](fig5.pdf){width=".48\textwidth"}

In weak confinement, Fig. \[fig:bond-ang-dist\](a), where the balance between excluded volume interaction and entropy of each chain makes it swell, we see a distribution of angles which by increasing the degree of confinement, tends slightly towards the smaller angles for longer segments, see SM [@SM_]. The distribution for flexible chain is indeed the bond angle distribution and due to the purely repulsive interaction between every other monomer, they cannot approach each
