Angle is a space between two lines or surfaces that meet at one point, which you measure in degrees.
A face of a polyhedron is one of the flat surfaces. These are two dimensional objects. Two faces meet at an edge, which is a line - a one dimensional object. Three or more edges meet at a vertex which is a point. A point has no dimensions.
The X and Y axes meet at the origin.

When in reference to architecture, arris refers to the sharp edge formed when two curved or flat surfaces meet. The surfaces must meet at a salient angle.
pyroxenes
... are straight lines where two planar surfaces meet.
it deviates its path and meet where water and air surfaces meet.
Yes
Many of the internal organs meet this criteria. Just to name a few: -The intestines (large and small) -The Appendix -The stomach -The brain
