semi circle
A semicircle?
a semi-circle
A line is not a polygon. A polygon is a closed figure with straight sides, while a line is a straight path with no endpoints.
A semicircle is an example of a figure with one straight line. It is a circle that has been split along the diameter.
There isn't such thing as a one sided polygon. The definition of a polygon is a closed figure with straight lines. So technically it is just a line.
A closed figures is one that has one consistent line making up the figure. There are no openings in the like. Example: a spiral.
A plane figure cannot be bounded by only one straight line. If the shape is bounded by lines which are not straight or by several straight lines the answer will depend on exactly what these are.
A straight line is a one dimensional figure in geometry
1. has at least 3 straight sides 2.closed figure 3. forgot the third one
It is a polygon, but only if it is all in one plane.
a stupid one A straight line segment.
It must be a plane figure. It must be closed. It must be bounded by straight lines. These straight lines must not cross one another.
