It is a polygon that fits the given description.
Try to decompose the figure into simple figures, for which formulae are known - such as triangles, rectangles, circular segments, etc.
helix
Figures that can be subdivided into simple figures.
A geometric solid. The answer is NOT polyhedron. A cone, for example, which is a figure made up of the most simple geometric shapes (a straight line) and a circle, is not a polyhedron.
A simple closed figure formed by three or more segments is called a polygon. Regardless of how many sides a polygon has, all polygons will have as many vertices as it has sides.
A triangle.
It is called its perimeter.
polygon
no, but an eight sided figure you could use is an octagon. a figure 8 may be a figure and closed but, it has no sides and no line segments.
A polygon, but only if all the line segments are coplanar.
If they are straight lines then it is a polygon.
It is a polygon that fits the given description.
Yes. A simple closed figure is counted as a polygon for a polygon is closed.
A polygon
A simple closed figure formed by line segments joined together. The point where the sides meet is called the vertex (vertices, plural). A regular polygon is formed when all the sides are equal. Polygons are named by the number of sides and angles they contain.
