  We have studied the distribution patterns of lateral density, arrival time
and angular position of Cherenkov photons generated in Extensive Air Showers
(EASs) initiated by $\gamma$-ray, proton and iron primaries incident with
various energies and at various zenith angles. This study is the extension of
our earlier work \cite{Hazarika} to cover a wide energy range of ground based
$\gamma$-ray astronomy with a wide range of zenith angles ($\le 40^\circ$) of
primary particles, as well as the extension to study the angular distribution
patterns of Cherenkov photons in EASs. This type of study is important for
distinguishing the $\gamma$-ray initiated showers from the hadronic showers in
the ground based $\gamma$-ray astronomy, where Atmospheric Cherenkov Technique
(ACT) is being used. Importantly, such study gives an insight on the nature of
$\gamma$-ray and hadronic showers in general. In this work, the CORSIKA 6.990
simulation code is used for generation of EASs. Similarly to the case of
Ref.\cite{Hazarika}, this study also revealed that, the lateral density and
arrival time distributions of Cherenkov photons vary almost in accordance with
the functions: $\rho_{ch}(r) = \rho_{0}\;e^{-\beta r}$ and $t_{ch}(r) =
t_{0}e^{\Gamma/r^{\lambda}}$ respectively by taking different values of the
parameters of functions for the type, energy and zenith angle of the primary
particle. The distribution of Cherenkov photon's angular positions with respect
to shower axis shows distinctive features depending on the primary type, its
energy and the zenith angle.
