Solid having only line segments as its edges is a
(a) Polyhedron
(b) Cone
(c) Cylinder
(d) Polygon
Solution:
Given, solid has only one line segment as its edges.
We have to find the name of the solid.
A solid is a polyhedron if it is made up of only polygonal faces, the faces meet at edges which are line segments and the edges meet at a point called vertex.
A cone is a three-dimensional shape that has a circular base and it narrows down to a sharp point called a vertex.
A cylinder is a 3D solid shape that consists of two identical and parallel bases linked by a curved surface.
Polygons are defined as plane (two-dimensional) and closed shapes that are formed by joining three or more line segments with each other.
From the definition of polyhedron, line segments meet at edges.
Therefore, the required solid is a polyhedron.
