  Time-reversal symmetry breaking allows for a rich set of magneto-transport
properties related to electronic topology. Focusing on the magnetic Weyl
semimetal Co$_3$Sn$_2$S$_2$, we prepared micro-ribbons and investigated their
transverse and longitudinal transport properties from 100 K to 180 K in
magnetic fields $\mu_0 H$ up to 2T. We establish the presence of a
magnetoresistance (MR) up to 1 % with a strong anisotropy depending the
projection of $H$ on the easy-axis magnetization, which exceeds all other
magnetoresistive effects. Based on detailed phenomenological modeling, we
attribute the observed results with unexpected form of anisotropy to magnon MR
resulting from magnon-electron coupling. Moreover, a similar angular dependence
is also found in the transverse resistivity which we show to originate from the
combination of ordinary Hall and anomalous Hall effects. Thus the interplay of
magnetic and topological properties governs the magnetotransport features of
this magnetic Weyl system.
