What does mean in geometry A closed geometric figure made up of three or more line segments.?

Answer 1

A closed geometric figure refers to any shape that is closed ie not open

for example the letter U is opened the letter O is closed.

an opened figure allows access to the inside without passing through the object itself (ie an opened doorway)

a closed figure is one you can't go from outside of to inside or visa versa without passing through the object. ie it doesn't have a hole in it.

3 or more means what it says

and a line segment is part of a line (note lines go on forever in both directions in geometry) with 2 end points. as differentiated from a ray which has one endpoint and goes off straight in one direction forever. (not bent or curved)

lines typically are drawn <------------------------------->
line segments ._________________.
and rays .------------------------------>

(sorry but that is the best I can do with typing)


so what you are referring to are triangles, squares, rectangles, rhomboids, trapezoids, etc.

any normal shape that is not round.

Answer 2

It means "a polygon".
