A shape made of lines is called a polygon. Polygons are two-dimensional figures formed by straight line segments that connect to form a closed shape. Common examples include triangles, squares, and pentagons. The sides and angles of polygons can vary, leading to different classifications such as regular and irregular polygons.
polygon
They're called lines.
a circle
A line segment
it if called a edge for a 3D shape
polygon
A shape made up of line segments is a shape with straight lines, or a polygon. for example, a square has straight lines, or is made up of line segments. A circle is not in that category because it has no straight lines, they are curved.
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
They're called lines.
a circle
A curvilinear pattern is a curvilinear shape ( a shape made completely of curved lines. no straight lines/edges) repeated across a plane.
Connect five lines together
A line segment
What is the surface included within a set of lines called?
I reckon, if a 70 sided shape is called a heptacontagon, and a 50 sided shape is called a pentacontagon, then a 40 sided shape might be called a quadracontagon, or something along those lines.
A pair of infinitely long parallel lines.
It is called a parallelogram. or a square........ or a rectangle.........
