You are watching: A polygon with all sides the same length is said to be
Regular polygons tend to look favor someone tried to do a circle out of some straight lines. In fact, if you have actually a polygon with very many sides, the looks a lot like a circle indigenous a distance.The sides and also vertices room evenly spread roughly a main point, and regular polygons room convex - all the vertices suggest \"outwards\".
In the number above, you can adjust the variety of sides making use of the controls on the right of the polygon. An amazing thing to keep in mind is that when the number of sides is rather high (say more than 17) the shape starts to watch a lot like a circle. In fact, as you keep including sides, the area of the polygon, the area that its incircle, and also the area that its circumcircle all converge ~ above the exact same value.
|Vertex||The peak (plural: vertices) is a edge of the polygon. In any kind of polygon, the variety of sides and vertices are constantly equal.|
|Side||The sides space the straight line segment that consist of the polygon. View Sides the a continuous Polygon for more information and also formulas used to calculate your length.|
|Apothem (inradius)||The apothem the a continuous polygon is the heat from the facility to the midpoint of a side. (or, the length of the line). It is additionally the radius that the incircle. See Apothem that a continuous Polygon|
|Radius (circumradius)||The radius is the street from the center to any kind of vertex. It is additionally the radius of the polygon\"s circumcircle, the circle the passes with every vertex. See Circumcircle of a continuous polygon|
|Central Angle||The angle at the center of the polygon make by two nearby radius lines. See central Angles the a constant Polygon|
|Area||See Area the a continuous Polygon|
|Perimeter||By definition, every sides room the very same length, so the perimeter is simply the size of a next times the number of sides.|
All vertices lie on a circle
In a continual polygon all its vertices lie on a circle. In fact, this have the right to be one of the definitions of a continual polygon: \"All sides space the same length and all vertices lie on a circle\". This one is also called the circumcircle. SeeCircumcircle of a continual polygon
Being it is provided is not enough
For a polygon to it is in \"regular\" it must have actually all political parties the exact same length and also all inner angles the same. The figure above is actually an example of anequilateral polygon since it has all political parties the very same length, yet it is not a constant polygon because its interior angles room not every the same.
