a tangent
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
Would be at at 90 degrees to the surface, in other words at right angles. So a line which was perpendicular to a horizontal surface would be vertical.
It's called the normal.

Line perpendicular to the surface.
Perpendicular is a line drawn over a surface at an angle of 90 degrees.
this is so stupid i wish you actually had answers!
