A regular polygon has all of its sides of equal length and all of its angles congruent.
7 sides, which makes it a heptagon. A polygon is any shape with 3 or more sides.
Octagon
At least more then 2 sides
Two equilateral triangles or one rhombus.
A 1980 sided polygon makes 1980 vertices.
A regular polygon has all of its sides of equal length and all of its angles congruent.
A football isn't a polygon because it has 2 sides curved which makes it an oval.A polygon doesn't have a curved side(s)
7 sides, which makes it a heptagon. A polygon is any shape with 3 or more sides.
Octagon
A square is a polygon because it is a closed geometric figure with line segments and no curved edges
The sum of all exterior angles of a polygon is 360 degrees. In a regular polygon, all of the exterior angle are equal, so there must be 360/72=5 sides of the polygon, which makes it a pentagon.
At least more then 2 sides
A polygon has no direction so the phrase "in the same direction" makes no sense. Consequently, the question has no meaning.
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.
Two equilateral triangles or one rhombus.
A ray. When there are no points, its a line. When it has two points, its a line segment.
