A rake is an angle of slope measured from horizontal, or in some contexts from a vertical line 90° perpendicular to horizontal. A 60° rake would mean that the line is pointing 60° up from horizontal, either forwards or backwards relative to the object.

Usage

Though the term may be used in a general manner, it is commonly applied in several specific contexts. The rake of a ship's prow is the angle at which the prow rises from the water (the rake below water being called the bow rake). A motorcycle or bicycle fork rake is the angle at which the forks are angled down towards the ground. See also
