We report on scaling properties of the angular dependence of the magnetoresistance of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} thin films below {ital T}{sub {ital c}}=88 K up to 20 T. As recently suggested by Kes {ital et} {ital al}. (Phys. Rev. Lett. 64, 1063 (1990)), the dissipation is only related to the transverse field component along the {ital c} axis. Breakdown of the scaling appears between the angle when the field is parallel to the superconducting planes and a critical angle ({similar to}1{degree}), which reflects the finite anisotropy of the compound. We interpret the dissipation in the tilted magnetic-field orientation as resulting from the easy motion of vortex kinks along the CuO{sub 2} planes.
