what is a closed geometric figure made up of three or more line segments?

Answer 1

The general answer is Polygon.

Polygons are named according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, e.g. pentagon, dodecagon. The triangle, quadrilateral, and nonagon are exceptions. For larger numbers, mathematicians write the numeral itself, e.g. 17-gon. A variable can even be used, usually n-gon..

Types of polygons :

triangle (or trigon) : 3 Sides
quadrilateral (or tetragon) 4 Sides
pentagon : 5 Sides
hexagon (or sexagon) 6 Sides
heptagon (avoid "septagon" = Latin [sept-] + Greek) 7 Sides
octagon 8 Sides
nonagon (or enneagon) 9 Sides
decagon 10 Sides
hendecagon (avoid "undecagon" = Latin [un-] + Greek) 11 Sides
dodecagon (avoid "duodecagon" = Latin [duo-] + Greek) 12 Sides
tridecagon or triskaidecagon (MathWorld) 13 Sides
tetradecagon or tetrakaidecagon (MathWorld) 14 Sides
pentadecagon (or quindecagon) or pentakaidecagon 15 Sides
hexadecagon or hexakaidecagon 16 Sides
heptadecagon or heptakaidecagon 17 Sides
octadecagon or octakaidecagon 18 Sides
enneadecagon or enneakaidecagon or nonadecagon 19 Sides
icosagon 20 Sides
triacontagon 30 Sides
tetracontagon 40 Sides
pentacontagon 50 Sides
hexacontagon (MathWorld) 60 Sides
heptacontagon 70 Sides
octacontagon 80 Sides
nonacontagon 90 Sides
hectagon (also hectogon) (avoid "centagon" = Latin [cent-] + Greek) 100 Sides
chiliagon 1000 Sides
myriagon 10,000 Sides
decemyriagon 100,000 Sides
hecatommyriagon (or hekatommyriagon) 1,000,000
Sides

Answer 2

A polygon. Depending on how many line segments there are,

3 : triangle
4 : quadrangle
5 : pentagon
6 : hexagon

etc etc

Answer 3

there can not be a geometrical closed figure of less than three lines. for ans see above

Answer 4

While all of these figures are polygons, they are also Jordan Curves.

There are Jordan Curves that are not polygons, though.
