What does a closed polygon look like?
A polygon is a closed plane figure with three or more sides that are all straight. A circle is not a polygon as it does not have straight sides. …
What is a polygon closed curve?
A polygon is one type of simple closed curve. A polygon is the union of three or more line segments whose endpoints meet. The segments are called the sides of the polygon. The points at which the segments meet (always the endpoints of the segments) are called vertices.
Does a polygon have to be closed?
The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon. A shape that is not fully closed is not a polygon.
Does a polygon have closed lines?
Polygons. A polygon is any closed, 2-dimensional figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.
What are closed polygons?
A polygon 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.

What must a regular polygon have?
To be a regular polygon, the flat, closed, straight-sided shape must also have another property. Every interior and exterior angle in the regular polygon is equal to every other interior and exterior angle, and every side is equal in length to every other side. A regular polygon has: Congruent (equal-length) sides.
What makes a polygon an open polygon or a closed polygon?
Polygons can be classified as open or closed. A polygon is open when the segments do not all connect at the beginning and end. That is, if we draw the polygon starting at one point, we finish drawing at a different point. A polygon is closed when the segments do connect at the beginning and end.
How are the different types of polygons classified?
Types of Polygon. Depending on the sides and angles, the polygons are classified into different types, namely: Regular Polygon; Irregular Polygon; Convex Polygon; Concave polygon; Regular Polygon. If all the sides and interior angles of the polygon are equal, then it is known as a regular polygon.
Which is an example of a non convex polygon?
Also known as a non-convex polygon, it is a polygon having at least one of its interior angles measuring more than 180°. Some diagonals of a concave polygon lie outside the closed figure. A dart or an arrowhead in quadrilaterals, some irregular pentagon and hexagon are common examples of the concave polygon.
What are the properties of an n sided polygon?
Properties 1 The sum of all the interior angles of an n-sided polygon is (n – 2) × 180°. 2 The number of diagonals in a polygon with n sides = n (n – 3)/2 3 The number of triangles formed by joining the diagonals from one corner of a polygon = n – 2 4 The measure of each interior angle of n-sided regular polygon = [ (n – 2) × 180°]/n
