A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
A Polygon is a figure with at least three straight sides and angles, and typically five or more.
To answer your question first here is the definition of polygon "a closed plane figure bounded by straight sides " So it makes no sense to count the sides in an open polygon since it is really not a polygon.
The definition of a regular polygons is a polygon that is both equiangular and equilateral. in a kite not all the sides are the same then its angles are not all equal then it is not a regular polygon.
an angle whose vertex is the center of the polygon and whose sides pass through adjacent vertices.
There is no such thing. A polygon, by definition, is 2-dimensional.
Polygons by definition have three or more sides. A pentagon has five sides. A pentagon is a polygon.
A polygon, by definition, has the same number of sides as it has angles. The question is therefore misguided.
A quadrilateral is a polygon with four sides and angles.
Yes. A polygon is by definition a shape enclosed by multiple sides - the smallest number of sides that enclose an area is three.
A polygon is a closed figure bounded by sides. A triangle is a closed figure bounded by three sides. Therefore, according to the definition of polygon triangle is a polygon.
This is the definition of a "regular" polygon.
Yes, the definition of a polygon is any closed figure with straight sides.
A Polygon is a figure with at least three straight sides and angles, and typically five or more.
A circle could be considered to have "no sides" in theory, however under this definition it is not a polygon. Also, a circle could be considered to have infinite sides. You could consider a point to be a no-sided polygon, but it's a stretch.
A trapezoid is a polygon with four sides including one pair of parallel sides.
A triangle, by definition, has three sides. A polygon with five sides is called a pentagon.
