In today’s post, we will take a look at open and closed polygonal lines.
But first, we need to know what polygons are: polygonal lines are several straight segments placed together.
Polygonal lines can be classified as open or closed.
- A polygonal line is open when the segments do not all connect at the beginning and end. That is, if we draw a line starting at one point, and we finish drawing it at a different point.
This is an example of an open polygonal line:
- A polygonal line is closed when the segments do connect at the beginning and end. That is, you start to draw the line at a point and finish at the same point.
This is an example of a closed polygonal line:
Do you know how to identify open and closed polygonal lines?
I encourage you to try to identify whether the following polygonal lines are open or closed. You will find the answers below.
