FAQs on RD Sharma Class 8 Maths Solutions Chapter 19 - Visualising Shapes
1. What are some of the important points to remember in Chapter 19 of Class 8 Maths?
There are a few points that you must remember as a Mathematics student of Class 8. The following points will help you solve the problems of the chapter easily and will also help to perform great in exams if you remember those points deeply. They are listed down below.
A polyhedron is a solid object enclosed by polygons.
The faces of a polyhedron are the polygons that make it up.
The line segments that connect the crossing faces of a polyhedron are known as its edges.
The vertices of a polyhedron are the points where the edges intersect.
2. What is the difference between a right pyramid and a regular pyramid?
If the perpendicular dropped from the base's vertex intersects the base at its center point, i.e. the center of the inscribed or circumscribed circle, the pyramid is said to be the right pyramid. To put it another way, the pyramid's vertex is perpendicular to the base drawn across its center. The pyramid is known as an oblique prism elsewhere.
On the other hand, if the base of a pyramid is a regular figure, all sides of the base are equal, it is considered to be a regular pyramid.
