Question

Match the geometrical shapes which form the object.

List \[1\]	List \[2\]
Ice-cream cone	Cylinder + Cylinder
Igloo	Cylinder
Lamp	Cone + Sphere
Pole	Hemisphere + Cylinder

Answer 1

Hint: We have studied shapes in geometry, let us recollect them. Basic 2D-Shapes are Square, Rectangle, Triangle and Circle and the basic 3D-Shapes are Cube, Cuboid, Cone, Sphere and Cylinder. We also have some other 3D-Shapes they are, Hemisphere and Conical frustum. Hemisphere is nothing but the half sphere and Conical frustum is half of the cone when its upper part is removed.

Complete step-by-step solution:
Our aim is to match the object to its relevant 3D-shapes. First let us draw the 3D-shapes that have been given in the option.
The given 3D-shapes are Cylinder, Cone, Sphere and Hemisphere.

Now let us draw the given objects using these 3D-shapes. First let’s draw the ice-cream cone using these 3D-shapes.

Thus, ice cream cones can be drawn using a cone and a sphere that is Cone + Sphere.
Now let us draw the igloo using these 3D-shapes.

Thus, igloo can be drawn using a hemisphere and a cylinder that is Hemisphere + Cylinder.
Let us now draw the lamp using these 3D-shapes.

Thus, a light lamp can be drawn using a cylinder alone.
Now let us draw the pole using these 3D-shapes.

Thus, a pole can be drawn using two cylinders that are Cylinder + Cylinder.
Hence, we have found the shapes of the objects given, now let us match them with the respective shapes.
Ice-cream cone = Cone + Sphere
Igloo = Hemisphere + Cylinder
Lamp = Cylinder
Pole = Cylinder + Cylinder
Thus, we have matched all the objects to their respective 3D-shapes.

Note: Any objects can be represented by using 2D or 3D shapes. We need to know all the basic 2D shapes and 3D shapes. We have studied shapes in smaller classes. The thing is that we need to have some basic knowledge of which shape can be attached perfectly to which shape. Even the lamp can be drawn using a frustum and cylinder, but here there is no other option thus we have drawn that kind of lamp. It all depends upon the option given to us.
