Characterizing polygons that are created when joining 2 vector layers

What is a vector layer and what is its characteristics?

A vector layer is a layer that allows you to edit lines that have already been drawn. You can change the brush tip or brush size, or change the shape of the lines using handles and control points. You can use the following tools on vector layers. The [Fill] tool cannot be used on vector layers.

• Direction.
• Magnitude.

What are the two characteristics of all vectors?

What is the characteristic of a vector space?

A vector space is composed of three objects, a set and two operations. Some would explicitly state in the definition that V must be a nonempty set, but we can infer this from Property Z, since the set cannot be empty and contain a vector that behaves as the zero vector.

What are the characteristics of a vector painting?

The characteristics of vector graphics are:

• Vector images are formed from a combination of individual objects consisting of points, lines and colors.
• Image size does not affect the quality of the displayed image, because it does not depend on image resolution.
• Has a relatively small size for the image file.
