A wet edge is a decorative arts term (faux finishing). It applies to the glazing process. The artist, while applying the glaze, works in sections on a wall. They must make sure that the glaze does not dry on the outer edge in order for it to be joined to the next section. If it does dry, the result is a "dry edge" that creates a line and ruins the entire look of the faux finish.

A straight line from the center of a circle to the outer edge is called a radius.
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
A separator or a horizontal line.
