Yes.
There is absolutely no point in naming an invisible angle!
This is a negative angle.

An angle can be named in four ways: by using the vertex and one point from each ray, such as ∠ABC where B is the vertex; by using just the vertex if it's the only angle at that point, like ∠B; by using a number associated with the angle, such as ∠1; or by using a three-letter notation that includes the vertex, like ∠XZY, ensuring that Z is the vertex. Each method provides a unique identification of the angle in question.
the name of an f angle is a corresponding angle
If the pair of angles are formed by two rays meeting at a point (see the superb figure below!) then it is difficult. The only way is to call one of them (angle y) a reflex or major angle, and the other (angle x) the minor angle. A B ____ y x \ ....\ .....C Otherwise, the angles can be named by using the names of the rays that form the angles, for example, if line DC meets line AB at C, (an even better figure!) D ...\ __\__ A C B then you have angle DCA to the left and DCB to the right.

The edges of facets -- where facets meet would be called by a geometric name: angle. You can read more about the names of cuts and their component faces/ facets, below.
Jim Angle's birth name is James Leslie Angle Jr..
I suppose you are looking for the name. The common name for a 90o angle is 'right angle'.
