When light is reflected from a plane surface of glass at the polarizing angle, the reflected ray is at right angles to the incident ray. This is because of Brewster's law, which states that the tangent of the angle of incidence is equal to the refractive index of the medium. At the polarizing angle, the angle of incidence is such that the reflected ray is completely polarized, and the reflected ray is at right angles to the incident ray.
