### Important Terms about Class 8 Maths Chapter 10

##### Can a polygon have for its faces a square and four triangles?

Yes, a polyhedron has its faces a square and four triangles which makes a pyramid on square base.

##### Is it possible to have a polyhedron with any given number of faces?

It is possible, only if the number of faces are greater than or equal to 4.

In Chapter 10 Visualising Solid Shapes, we have to learn about different shapes with 3-D view form Top side or lateral sides. This also provides the information about how to find number of faces, vertices and edges of a solid figure. Each of these solids is made up of polygonal regions which are called its faces; these faces meet at edges which are line segments; and the edges meet at vertices which are points. Such solids are called polyhedrons. A pyramid is a polyhedron whose base is a polygon and whose lateral faces are triangles with a common vertex. (If we join all the corners of a polygon to a point not in its plane, you get a model for pyramid).

##### Euler’s Formula

From Euler’s Formula, in a polynomial, the relation F can be counted in the number of faces F, the number of vertices V and the number of edges E. Euler’s Formula: F + V – E = 2. From this formula, the number of faces in any polynomial can be found.
