Although a polygon is usually thought of as a two-dimensional figure with at least three sides, there is nothing in the definition of a polygon that prohibits its use for the classification of a one-sided figure. A one-sided figure is known as a henagon or a monogon. A polygon, by definition, has as many vertices as it has sides, so a single-sided polygon would have to, in order to meet that criterion, curve in on itself so that the two ends of the side meet to form a vertex. In order for the polygon to not be curved, it would have to be made up of two straight lines (this figure is known as a digon). So no, a polygon cannot be a single straight line.

How can you use a coordinate plane to draw a polygon?

You do not need a coordinate plane to draw a polygon. A polygon is simply a plane shape whose boundaries are straight line segments that meet at their ends but do not cross. So draw any number of points and draw straight ines from one to the next, and on to the next, and so on except that you must not cross an existing line and the last line must end at the starting point.

Is a Trapezoid a polygon?

Yes, it has sides that are straight line segments. Exactly one pair of opposite sides is parallel. Polygons do not have curved sides.


How many sides does a regular polygon have if the measure of one interior angle is 105?

Such a polygon is not possible because it would have 4.8 sides.Angles on a straight line are 180 degrees and 105+75 = 180Angles around a polygon are 360 degrees and 360/75 = 4.8


Which shapes have no parallel sides?

The only polygon that absolutely positively never has any parallel sides is a triangle. Any other shape comprised of four or more straight line segments could have one or more pairs that are parallel.


What is the difference between a polygon and a plane figure?

A polygon is a plane figure which comprises one area bounded by three or more straight line segments. A general plane figure can have curved boundaries or sides that cross each other.

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 straight line that joins one vertex to another vertex.


What is a polygon that has one side called?

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.


What polygon has a long curved line?

A polygon is made up only of line segments. If a 2-dimensional closed figure has even one curve line, then it is not a polygon.

How do you draw a 9 sided polygon?

Draw a straight line segment. From one of its ends, draw another straight line segment. From the end of this straight line, draw another straight line segment which does not touch any of the existing lines. Repeat the same 5 more times. From the end of this last line, draw a straight line to the start of the first line. You may need to tweak some of the intermediate lines so that the last line does not intersect an existing line. That is it! A plane area enclosed by 9 straight lines = a 9-sided polygon.


What is the name of a polygon with one sides?

A line?? It's impossible to have a polygon with only one side, hence the "poly" meaning many.


How do you determine whether a polygon is convex or non-convex?

No interior angle of a convex polygon can exceed 180 degrees. A non-convex polygon has at least one reflex angle (> 180 degrees). Alternatively, a polygon is convex if, given any two points on or inside the polygon, the straight line joining the two points must lie wholly on or inside the polygon. In a non-convex polygon, it is possible to find a pair of points such that the straight line joining them lies outside the polygon for at least some of its length.
