Question

What are vertices, edges, faces of 3D figures. explain with an example

Answer 1

Answer:

In a polyhedron, three or more edges meet at a point to form a vertex. Some examples of polyhedrons are the cuboid, cube, pyramid, triangular pyramid etc.

The edge of a solid figure is the line segment where two faces meet.

A vertex (plural: vertices) is the corner that is formed where the ends of the line segments of two or more faces meet. A sphere is a solid figure that has no faces, edges, or vertices. ... A pyramid has one base and at least three triangular faces.

Flat surfaces enclosed by edges are called faces. A face of a solid shape is a plane or 2d figure

Answer 2

Answer:

Step-by-step explanation:

Edges - Line segments present in a figure is called edges

Example -  Cube has 12 edges that is it has 12 line segments .

Vertices - Point where 2 or more line segments meet is a vertice

Example - Cone has 1 vertice as it has only 1 point where 2 line segments meet .

Faces - Number of plane figures the figure has is called faces

Example - Cuboid has 4 rectangles & 2 squares so it has 6 faces in total .
