CHAPTER 10 VISUALISING SOLID SHAPES
When a solid object has only two measurements it is called a 2 dimensional shape.
When a solid object has three measurements- length, breadth and depth, it is called a 3 dimensional shape.
3D shapes objects have a different views from different positions
A map depicts the location of a particular object in relation to other objects.
A polyhedron is a solid made up of polygonal regions called faces. These faces meet at edges and edges meet at vertices. For any polyhedron,
F + V – E = 2
Where ‘F’ stands for the number of faces, V is the number of vertices and E stands for number of edges. This is Euler’s formula.
