• There are Three Different Kinds of Shapes:
  

1. One-dimensional shapes: Shapes with only one dimension: length. Consider the following example: a line. 

2. Two-dimensional Shapes: Two-dimensional shapes have two dimensions: length and breadth. A polygon, a triangle, a rectangle, and so on are examples of shapes. Two-dimensional figures are sometimes referred to as 2-D figures.

3. Three dimensional Shapes: Solid objects and shapes with length, breadth, and height or depth are referred to as three-dimensional shapes. Cubes, cylinders, cones, cuboids, spheres, and other geometric shapes are examples. 

4. Faces: A three-dimensional figure's face is a flat surface.

5. Edges: An edge is a line segment that connects two faces of a solid.

• Polyhedron: A three-dimensional figure with polygonal faces. 

• Prism: A polyhedron with congruent polygons on the bottom and top faces (known as bases) and parallelograms on the lateral faces. The shape is known as a right prism when the side faces are rectangles.

• Pyramid: A polyhedron with a polygon base and triangle lateral sides.

• Vertex is a place on a graph where three or more edges intersect.

• Base: A polyhedron's base is the face on which it is named.

• $F+V-E=2$ is Euler's formula for any polyhedron, where $F$ denotes the number of faces, $V$ the number of vertices, and $E$ the number of edges.

• Object recognition in 2D and 3D.

• Differentiating between shapes in nested objects.

• Views of 3D objects vary depending on their position.

• Mapping: A map shows where one object or place is in relation to other objects or places.

• Symbols are used to represent various objects and locations.

• In a map, there is no reference or viewpoint.

• Maps have a scale that is predetermined for each map.

• Convex: A line segment connecting any two points on a polyhedron's surface lies wholly inside or on the polyhedron. Cube, cuboid, tetrahedron, pyramid, prism, and so on. 

A Quick Overview of Class 8 Maths Chapter 10 Visualising Solid Shapes 

Class 8 Maths Chapter 10 Visualising Solid Shapes will introduce the Class 8 students about visualising solid shapes, View of 3D-shapes, Mapping Space Around us, and  Faces, Edges and Vertices of three-dimensional shapes.  Let's now discuss the topics, and subtopics covered in this chapter.

Ex.10.1 - Introduction to Chapter

In your previous classes, you must have studied different solid shapes and plane shapes. Plane shapes are also known as two-dimensional shapes as they only have two measurements, such as length and breadth, whereas solid shapes are known as three-dimensional shapes as they have three measurements, such as length, breadth, and height. Also, the solid shapes fill up some space. Two- and three-dimensional shapes are also named as 2-D and 3-d figures.

Ex.10.2 - View of 3D - Shapes

In this section, you will learn the views of different three-dimensional shapes such as cones, cylinders, cubes, spheres, etc. You will learn that three- dimensional objects can be drawn from the perspective as these look different from different positions. You will find that 3-d shapes have a top view, front view, and side view. A few real-life examples are given to make you understand the concept clearly.

Ex. 10.3 -  Mapping Around Us

In your previous classes, you must have used different maps. In Geography, your teachers must have asked you to mark rivers, mountains, states, countries, cities, etc. on a map. In history, your teachers must have asked you to locate a certain place where some event had occurred in the past.

In this section, you will learn how to read maps. What can you conclude and understand while reading maps? What information do we get from maps, and what does it not include?

Ex.10.3 - Faces, Edges, and Vertices

In this section, you will study faces, edges, and vertices of three-dimensional shapes. Yow will also learn the total number of faces, edges, and vertices different 3-D shapes include.

Students should have a thorough knowledge of different solid and plane shapes so that they do not face any problems in solving the questions based on it.
